Sir Howard Montagu Colvin

Elected a Fellow of the Society on 1 May 1980

The following obituary, written by Richard Hewling, FSA, was first published in the Independent on 01 January 2008.

Howard Montagu Colvin, historian: born Sidcup, Kent 15 October 1919; Assistant Lecturer in History, University College London 1946-48; Fellow, St John's College, Oxford 1948-87 (Emeritus), Tutor in History 1948-78, Librarian 1950-84; CBE 1964; Reader in Architectural History, Oxford University 1965-87; President, Society of Architectural Historians of Great Britain 1979-81; CVO 1983; Kt 1995; married 1943 Christina Butler (died 2003; two sons); died Oxford 15 October 1919 28 December 2007.

Howard Colvin was the greatest architectural historian of his own time, and perhaps ever. He admired his seniors Sir Nikolaus Pevsner and Sir John Summerson, but both of them were indebted to him for the factual basis on which their judgements were formed; revising Summerson's 1945 Georgian London in 2001, Colvin wrote "[its] combination of brilliant thought and writing with factual carelessness is quite difficult to handle".

The intellectual model whom he regarded as almost faultless was Robert Willis, whose Architectural History of the University of Cambridge (1886) pioneered the solution of archaeological problems by absolute mastery of the documentation, yet Colvin's six-volume History of the King's Works (1963-1982) alone was a greater achievement than Willis's. In addition, Colvin produced what might have remained the authoritative Biographical Dictionary of English Architects 1660-1840 in 1954, had he not expanded it to include Scotland and the years 1600-1660 in 1978 (with the title A Biographical Dictionary of British Architects 1600-1840), and brought out a revised edition in 1995.

It is possible for the very well-informed and very diligent to find an error, or even two, in 1,264 double-column pages of 10-point text, but difficult – and unusual. At the time of his death, Howard Colvin had nearly completed proof-reading the fourth version of this astonishing work, whose versions since 1954 have been the starting point of all historical research on the architecture of early modern Britain.

Howard Colvin was the son of Montagu Colvin, a Vickers executive and stamp dealer of lowland Scots descent. Howard won scholarships to more than one public school, but his father chose Trent College, Nottingham, because it seemed to be the best bargain. An urbane and broad-minded history master, Mike Morgan, provided succour in an evidently harsh environment by allowing Howard to visit churches instead of playing games; thus, aged 19, he published his first historical paper, the first of eight on Dale Abbey, Derbyshire, in 1938. He read history at University College London, and in 1943 he married Christina Butler, daughter of the professor of Latin there, sister of the psephologist David Butler, and herself an authority on, inter alia, her Anglo-Irish ancestress Maria Edgeworth.

In 1940 Howard Colvin joined the RAF "because it seemed less bad than the army". Fairly quickly, the RAF lost his records and was unable to do anything with him and a few other unrecordeds except march them from Garstang to Blackpool for lunch and march them back again in the afternoon. On one occasion, lunch was served by a girl whom he had known at university and whose father was an under-secretary in the Air Ministry; she just had time to tell him that her father was looking for archaeologists as photographic interpreters, so in due course he found himself promoted from Aircraftman Second Class to Flight Lieutenant and posted to Malta.

He worked in a limestone tunnel which had an opening in the cliff above the Grand Harbour in Valletta, and during breaks he could use this grandstand to watch the Stukas screaming down onto the British ships at anchor. He recalled the deafening noise of the anti-aircraft barrage and the sight of spent shell cases tumbling from the gun turrets and rolling over the ships' decks until the sailors kicked them overboard.

His unit identified Italian warships from photographs. He was surprised once when a visiting senior officer said "Well done, boy" after one of his identifications, and assumed that this man's evident prior knowledge had come from espionage; only later did he realise that it came from Enigma. He was particularly pleased that he interpreted white lines in dawn photographs as dew on telegraph wires; he persuaded a daring pilot to test this with a low-level photo of Taormina, and convinced his superiors that, as civilian telegraph wires had been dismantled, all the white lines were leading them to Kesselring's headquarters.

In 1946 Colvin was appointed an assistant lecturer at UCL, and in 1948 he obtained a fellowship at St John's College, Oxford, where he remained for the rest of his life, as Tutor (1948-78), Librarian (1950-84), and Emeritus Fellow (1987-2007). As Tutor, he taught the regular Oxford history syllabus, but he managed to add a special paper on English architectural history 1660-1720, then the only form of art history available to Oxford undergraduates, for which he was rewarded by a Readership in 1965.

Oxford respected his productivity and meticulous scholarship, but, for long without art historians of its own, may not have realised that he was even more respected outside its walls; he was never given a chair.

Meanwhile he had a public service career in parallel. He was a commissioner of the Royal Fine Art Commission (1962-72), a commissioner of the Royal Commission on Historical Monuments for England (1963-76), a member of the Historic Buildings Council for England (1970-89), its chairman (1988-89) and chairman of one of its sub-committees (1970-89), a commissioner of the Royal Commission on Ancient and Historical Monuments for Scotland (1977-89), president of the Society of Architectural Historians of Great Britain (1979-81), a commissioner of the Royal Commission on Historical Manuscripts (1981-88), a member of the reviewing committee on the Export of Works of Art (1982-83) and a commissioner of English Heritage (1984-89).

He was an indefatigable attender and a valuable and judicious contributor to discussion until he retired at the age of 70. It was doubtless this unpaid work which was rewarded with his knighthood by John Major's government in 1995; his nomination was supported by two cabinet ministers, the head of the Royal Collection, the chairman of the Royal Commission on Ancient and Historical Monuments for Scotland, a former vice-chancellor, three former and one current head of Oxford houses, two Regius Professors of history, a former director of the V&A and the obiter dicta of the late Sir John Summerson.

Colvin will be most remembered for his scholarly output, unstoppable up to the moment of his death. Although chiefly a historian of architecture, he also wrote two institutional histories (of a religious order and a government department), the history of a profession (architecture), and three histories of localities (Deddington, Holme Lacy and Irford). Unusually he was both a medievalist and a post-medievalist. His first book was The White Canons in England (1951), and the first two volumes of The History of the King's Works (1963) remain the definitive history of the castles, palaces and religious foundations of the medieval kings. He responded to the places to which the war took him with articles on Victorian Malta, Aberystwyth's architecture and Georgian Marlow.

Architecture and the After-Life (1991) covers funerary buildings as far apart as Mesopotamia, Africa, Sweden and Ireland. Although he wrote little about 20th-century architecture, he took a critical interest, and, as a Fellow of St John's, was a patron of Sir Richard MacCormac. He was one of the first architectural historians to appreciate the contribution made by amateur architects, especially in the 18th century, and was one himself, designing an extension to the Senior Common Room at St John's and his own house in north Oxford.

However, the field in which his greatest achievement lies is early modern British architectural history. His three (soon to be four) successive biographical dictionaries both established the methodology and laid the factual foundation on which all other scholars have built. The idea was conceived, he said, in response to the unscholarly habit of attributing even the most commonplace buildings to one or two well-known architects of the appropriate period. Sir Albert Richardson, then head of the Bartlett School of Architecture, was a prime offender. Seeing himself as an architectural Berenson, he signed certificates of authentication which one used to find hanging in churches and country houses.

Colvin began the first dictionary while still an undergraduate and, surprisingly, was able to work on though the war, finding that the garrison officers' library in Malta had been richly stocked with 18th-century architectural books by the Royal Engineers responsible for the island's fortifications.

Reviewing the work at the launch of the 1995 edition, he claimed that the 1954 edition had no more than 60 stylistic attributions (to several thousand documented ones). "Of these," he wrote: 14 had been confirmed (by documentary evidence) by 1978 and only three proved to be wrong. In the second (1978) edition there were 128 such attributions, of which 14 have since been confirmed and 12 abandoned (though not necessarily shown to be wrong).

Buildings being more abundantly documented than paintings, architectural historians have an advantage over historians of painting, who have to depend more on connoisseurship. But they also have the advantage of Colvin's methodological establishment, his factual groundwork and his example.

In default mode, Howard Colvin's face expressed his formidable powers of concentration, important moments being indicated by balletic eyebrow movements; but this was often replaced by the most engaging smile and occasionally by spasms of abandoned laughter. He and I shared a taste for Georgian grandees with evocative names (Sir Rushout Cullen, Sir Carnaby Haggerston and Hurt Hurt).

He was a tiny man, who loved alpines and had microscopic handwriting. His work was both helped and hindered by innumerable correspondents, either reporting discoveries or seeking endorsements. To keep to his formidable programme, he had no choice but to reply by return, sometimes advising in surprising detail, but always aware of the difference between the significant and the trivial, and particularly alert to "arid art-historical debate". Correspondents reporting what they believed to be a discovery had to be inured to reading "When I saw this drawing in an attic at Blandings Castle in 1950. . ." in reply. His letters are as rich a source of British architectural history as his 132 publications.

The following obituary was first published in theTimes on 01 January 2008.

Sir Howard Colvin, CVO, architectural historian, was born on October 15, 1919. He died on December 27, 2007, aged 88.

Sir Howard Colvin wrote what is almost certainly the finest reference book of modern times produced by a single author — A Biographical Dictionary of English Architects 1660-1840 (1954), revised and expanded in 1978 to cover the whole of Britain from 1600 to 1840 in 1978 and revised again in 1995 . While most great works of reference tend to be compilations of information from published sources, Colvin went, to an unprecedented extent, to the archives themselves. The speed and dexterity with which he would unfold and assess bundles of 17th and 18th-century papers, transcribing everything of note in his neat, tiny, unvarying hand was a marvel to behold.

His lifelong interest in architecture began as a schoolboy in his native Kent, and in earnest as a boarder at Trent College, near Derby, where he was able to escape cricket and cycle round the Midlands in search of medieval churches, castles and ruined abbeys.

At University College he decided to apply “the ordinary processes of historical scholarship” that he was learning in the history department to put an end to what a contemporary described as “the muddled vapourings which passed for architectural history between the wars.”

A two-year stint on the embattled island of Malta beginning in 1941 was not the interruption it might have been, for as well as practising his eye scrutinising aerial photographs, Colvin was quickly at home in Valletta's three libraries, the Royal Malta Library founded by the knights in the 18th century, the Garrison Officers' Library founded by the British in the 19th century, and the modern British Institute Library, all of which remained open and undamaged by the bombing. The Garrison Library had numerous important Georgian architectural books such as The Antiquities of Athens, acquired by use by the Royal Engineers who designed public buildings as well as fortifications.

Reading Walpole's Letters and Nichol's Literary Anecdotes Colvin realised the importance of culling information about architects and their commissions from the widest range of, often unlikely, sources. By scouring long forgotten periodicals and county directories as well as archives, and systematically seeking out the authorship of churches, town halls and country houses, Colvin discovered the names of numerous provincial architects and master builders who would never have come to light if he had researched known names purely on a biographical basis.

His mastery of archives led him to establish friendly relations with the archivists of the new County Record Offices established by the government after the war. In the Public Record Office he found the long forgotten Chancery Masters' Exhibits — papers produced in evidence in family lawsuits, which proved to include such treasures as the business letter-book of Mrs Coade's artificial stone manufactory and the records of the commissioners for rebuilding the town of Warwick after the fire of 1694.

Many of his early travels to archives and buildings were made by motorbike, but soon he was travelling by limousine with the late Rupert Gunnis, author of a parallel Dictionary of British Sculptors, whose connections ensured that they could usually gain free access to the muniment room of any great private house, and that, when every hotel room at York was taken, they were given a bed at Castle Howard.

Ecclesiastical documents were unexpectedly those which were most difficult to access — Colvin noted forcefully that a previous chancellor of the Diocese of London was “the sworn enemy of historians” while in 1949 he found the verger of Malmesbury Abbey tearing out pages from the churchwardens' accounts to light his pipe.

Though gentle of manner, Colvin waged a sustained war against what he called “irresponsible attributionism”.

His barb was aimed especially at the architect-historian Sir Albert Richardson who, Colvin said, saw himself as an architectural Berenson, signing “certificates of authentication which one used to find hanging in churches and country houses”. The first edition of the dictionary, Colvin pointed out with his usual exactitude, contained just 60 attributions, 14 of which were subsequently confirmed by documentary evidence.

Each biographical entry was a miniature, or sometimes substantial, essay appraising the ability of an architect, scrupulously recording every source, including the numerous titbits which reached him by letter or card. Colvin never used a computer or even a typewriter but built up a massive card index which went straight to John Murray, his publishers.

In 1965 Colvin's already unprecedented contribution to his field was recognised when his college, St John's, granted him a personal readership in architectural history, allowing him to concentrate his research and writing on architecture, though he continued to teach medieval history until 1978.

Parallel with the dictionary he took a significant role in writing and editing the magisterial six-volume History of the King's Works, tracing, with characteristic thoroughness, the pattern of royal building and patronage from Saxon times to 1851, embracing the castles, palaces and hunting lodges of the Middle Ages, as well as hospitals, colleges and ecclesiastical foundations (including much of Angevin and Plantagenet France, as well as England and Wales). Going back always to the original archives, Colvin once again astounded his colleagues by the speed and care with which he unrolled medieval parchment and deciphered handwriting. Unusually, the authors were paid by the word (and well), the old Office of Works having complete confidence that Colvin would not admit a single superfluous phrase.

In 1995 Colvin joined Sir John Summerson and Sir Nikolaus Pevsner as one of the select group of architectural historians to earn knighthoods.

Though quietly spoken, Colvin was an assiduous committee man, serving on the Historic Buildings Council for England 1970-84, the Royal Commission on the Ancient and Historical Monuments of Scotland 1977-89, the Royal Commission on Historical Manuscripts 1981-88, the Royal Fine Art Commission 1962-72, the Royal Commission on Historical Monuments for England 1963-76 and as President of the Society of Architectural Historians 1979-81.

His articles in Country Life on Calke Abbey were the touchstone of the campaign in 1983 to save this great, yet virtually unknown, country house in Derbyshire from break-up and when one peer rashly suggested it was full of skiploads of junk, Colvin replied famously suggesting that he look closer at a collection which “includes Bronze Age swords, silver by Paul Delamerie, 18th-century Chinese silk hangings in mint condition, an autograph musical score by Haydn..”.

Colvin's principal publications include The White Canons in England, 1951; A Catalogue of Architectural Drawings in Worcester College Library, 1964; The Country Seat (edited with John Harris), 1970; Building Accounts of King Henry III, 1971; Unbuilt Oxford, 1983; All Souls: An Oxford College and its Buildings, 1989; and Architecture and the After-Life, 1991. As recently as September this year he astounded his peers in a conference talk, convincingly identifying the designer of Wotton House in Buckinghamshire as John Fitch, builder of the west front of Chatsworth. Shortly before his death he had not only approved the proofs of the extensively enlarged fourth edition of his dictionary but put the finishing touches to the index.

He married Christina Edgeworth in 1943. She predeceased him and he is survived by their two sons.

The following obituary was first published in the Daily Telegraph on 7 January 2008.

The original published version has a photograph of Sir Howard Colvin in the Codrington Library, All Souls, Oxford.

Sir Howard Colvin, the architectural historian who has died aged 88, was the author of the magisterial Biographical Dictionary of British Architects 1600-1840.

Colvin was one of three architectural historians to be knighted, but while Sir Nikolaus Pevsner could achieve the synoptic overview and illuminating analysis and Sir John Summerson was admired for his cool judgment and elegant prose, both depended upon Colvin, almost a generation younger, for the essential basis for historical assessment: facts, indisputable facts, based on first-hand archival research.

Indeed, in posthumously revising Summerson's classic, Georgian London, first published in 1945, Colvin found its "combination of brilliant thought and writing with factual carelessness hard to handle". It was Colvin's achievement to place British architectural history on a sound scholarly basis rather than rely on connoisseurship and myth.

Colvin's Biographical Dictionary of English Architects 1660-1840 appeared in 1954. So essential did it become as a reference work that a second edition, expanded in scope and which also encompassed Wales and Scotland, appeared in 1978.

An assiduous and generous correspondent, Colvin was the first to acknowledge his debt to other historians and researchers, notably Rupert Gunnis, Lawrence Stone and the Reverend Basil Clarke, as well as to the many librarians and county archivists who helped him, but the meticulous thoroughness of the dictionary, enlivened by succinct characterisations of both architects and their creations, was entirely his own achievement.

A particular strength was his understanding of the nature of the architectural profession in the past, and that it was not like the present, as many architect-historians had assumed. Colvin was therefore particularly pleased that through his research he rediscovered both the builder-architects, like the Smiths of Warwick, and the amateur gentleman-architects.

In 1995 a third edition was published and its author announced that: "There won't be another in my lifetime." This may seem prophetic, especially as Colvin never came to terms with the computer and continued to amass information by recording it on cards in his minuscule handwriting. But he lived to see the forthcoming fourth edition in proof and was putting the finishing touches to the index when he died.

Colvin, along with a fellow student at University College London, first thought of writing a biographical dictionary in 1938 or 1939 as, although studying Medieval History, he was already interested in the Classical architecture of the 17th and 18th centuries.

War then intervened but, curiously, this proved almost to be a blessing in disguise. Having joined the Royal Air Force in 1940, Colvin found himself posted to Malta as a photographic interpreter during the siege. Despite the incessant bombing of the island, he not only encountered Mediterranean Baroque for the first time but discovered three good libraries in Valetta which escaped damage and which furnished him with many architectural books essential for his task. After the war, academic posts enabled Colvin, now alone, to pursue the dictionary.

It is difficult now to appreciate just how generally amateur and backward architectural history was at the time. Colvin was particularly infuriated by Sir Albert Richardson, the self-appointed "Last of the Georgians", who, for a fee, would issue certificates to the owners of buildings which assured them that they were designed by Nicholas Hawksmoor or Henry Holland, or whoever.

Furthermore, many archives were then impenetrable or carelessly run. In his Essays in English Architectural History (1999), Colvin recalled how he found the verger of Malmesbury Abbey tearing out pages from the churchwardens' accounts to light his pipe. Then there was the Chancellor of the diocese of London, "the sworn enemy of historians [who] would not admit a Regius Professor of Ecclesiastical History to the records in his care, let alone a mere don like myself".

Colvin also had to cope with thefts of drawings from important archives, with the funerary monuments to architects being destroyed, with so many buildings being demolished unrecorded before he had a chance to see them: "all these," he recalled, "added a melancholy excitement to the pursuit of architectural history in the earlier years of the century and are not wholly unknown even today."

Howard Montagu Colvin was born at Sidcup, Kent, on October 15 1919. Although he won scholarships to several public schools, his father, Montagu Colvin, an executive at Vickers and a stamp dealer, of Lowland Scots descent, sent his son to Trent College, between Nottingham and Derby, as it seemed to be the best bargain.

This bleak environment was mitigated by a broad-minded history master allowing the young Colvin to visit churches rather than play games, and he began his many purchases of old architectural books in the market at Derby.

After leaving the RAF in 1946, Colvin became an assistant lecturer at University College London, where he had been an undergraduate. Two years later he became a Fellow of St John's College, Oxford, to which institution he remained attached - and devoted - for the rest of his life, becoming Emeritus Fellow in 1987.

As Tutor, Colvin taught the regular history syllabus but eventually managed to add a paper on English architectural history. The university never fully exploited his talents or his eminence, however, and although Colvin became a beacon for younger architectural historians all over Britain, he was never given a chair nor - whether for better or worse - is architectural history taught as a separate discipline at Oxford.

Colvin was far from being a remote Oxford don, however, and his conscientious public service was rewarded by a knighthood in 1995. He served on the Royal Fine Art Commission, was a commissioner of the Royal Commission on Historical Monuments for England and afterwards for English Heritage; he also sat on the Royal Commission on Historical and Ancient Monuments for Scotland and the Royal Commission on Historical Manuscripts and he sat on the reviewing committee on the Export of Works of Art.

Both he and his fellow members were dismayed when he was retired from the then English Heritage Advisory Committee in 2000 when he still had so much to offer. A founder member of the Society of Architectural Historians in 1958, Colvin served as its president in 1979-81. Somehow he also found time to write many other books and articles as well as catalogues of architectural drawings.

He was general editor of The History of the King's Works, the story of public building in England, and was largely responsible for the first two volumes dealing with the medieval period. Amongst his other books, Unbuilt Oxford (1983), Calke Abbey, Derbyshire. A Hidden House Revealed (1985), and Architecture and the After-Life (1991) deserve mention.

This indefatigable lexicographer was far from being a harmless drudge. Small and neat in stature, Colvin could seem vaguely reminiscent of a benign furry animal, but there was often a mischievous twinkle in his eye and he was adept in getting his own way.

He would recount, with a degree of glee, how he was instrumental in ensuring that his college did not pursue the conservative design for new buildings by Sir Edward Maufe, the architect of Guildford Cathedral, but commissioned a modern building instead, designed by Michael Powers of the architects' Co-Partnership.

Colvin, indeed, was not a detached historian of architecture but actively interested in contemporary practice. He himself designed an extension to the Senior Common Room at St John's as well as his own house in Plantation Road in North Oxford where his garden was a particular delight.

Nor was he narrow in his appreciation, for he moved on from modernism to Post-Modernism and was very pleased with the more recent new buildings at St John's designed in a modern Soanean manner by Richard MacCormac. "British architecture has improved since the 1960s," he said in 1995. "Whatever its failings, Post-Modernism has produced a convincing new commercial vernacular and a regard for context."

For the Victorians Colvin had less regard but, surprisingly perhaps, he once contemplated writing about the great late 19th-century church architect Temple Moore. Nevertheless, he would not expand the scope of his Biographical Dictionary beyond 1840.

The continuing absence of a successor volume merely emphasises Colvin's colossal achievement in identifying and cataloguing the many architects who worked in Britain in the period from Inigo Jones to Charles Barry.

In 1943 Colvin married Christina Edgeworth Butler, the daughter of the professor of Latin at University College London, and nursed her through a long illness until her death in 2003. They had two sons.

The following obituary, by John Newman,FSA, was first published in the Guardian on 15 January 2008.

Howard Montagu Colvin, architectural historian, born 15 October 1919; died 27 December 2007.

Sir Howard Colvin, who has died aged 88, was the leading historian of British architecture and a scholar of astonishing productivity. His knighthood in 1995 confirmed his position as doyen of the discipline. His most important achievement was the dictionary of British architects, on which he was constantly at work for almost 70 years, beginning as an undergraduate in the late 1930s and ending only at his death. First published in 1954 as A Biographical Dictionary of English Architects 1660-1840, it was reissued in expanded form and as "a much more considered affair" in 1978, bringing in both Inigo Jones and the impressive achievements of Scottish architecture. A third edition came out in 1995 and in the last months of 2007 he was putting the finishing touches to the fourth.

Colvin's objective was simply to lay to rest what he called the "irresponsible attributionism" whereby "anything at all baroque was apt to be given to Hawksmoor, anything elegantly neo-classical to Henry Holland" and to bring to light the achievements of the amateur architects and, above all, the provincial builder-architects who were the real creators of our much admired Georgian towns and villages.

To compile the dictionary required the widest possible reading in the sources for the study of British culture in general; some of the key works he first read, surprisingly, in the garrison officers' library in Malta, where he was stationed as an RAF officer from 1941 to 1943. It also meant delving into archives in the Public Record Office, in diocesan offices and parish chests and in the muniment rooms of country houses. Such enjoyable treasure hunting led to many exciting discoveries. The dictionary provides lists of documented works of architecture by hundreds of designers and thumbnail biographies.

Colvin's other great publishing project was the six-volume History of the King's Works, published from 1963 to 1982, of which he was general editor and part author. This, the official history of the office of works, was "a study of the interrelation of government and architecture in England from the Middle Ages to the mid-19th century". Here he was not his own master; but it was through his talent as organiser and editor for more than 30 years that an enterprise that could easily have become bogged down was brought to a smooth conclusion.

Colvin was brought up in suburban north-west Kent, and educated at Trent college, Nottinghamshire, where, in the summer, he was "allowed to opt out of cricket and bicycle round the Midland countryside in search of medieval architecture". His first publication, aged 19, was on Dale Abbey, Derbyshire. He then read history at University College London, and, in 1946, was appointed to a lectureship there. In 1948, however, he was elected to a fellowship at St John's College, Oxford, where he remained for the rest of his career. Perhaps his most enduring contribution to his college was, as a member of its building committee from 1956, to persuade it to jettison plans for a neo-Georgian building by Sir Edward Maufe in favour of something representative of new architectural thinking. With the help of John Summerson, Colvin led the college to the Architects Co-Partnership, whose striking block of student rooms built in 1958-60 became the harbinger of a revolution in Oxford's college architecture. He subsequently designed his own compact house in north Oxford.

As a teacher Colvin's most important contribution was to establish a special subject in architectural history at Oxford, a university notoriously dismissive of the visual arts. Many of his pupils have gone on to become leaders in the field. In 1965 he was appointed university reader in architectural history.

Colvin served assiduously on many commissions and committees. His informed contributions often swayed a discussion, or brought it to an abrupt and decisive halt. One of his most successful campaigns was to save Calke Abbey, Derbyshire, and its contents for the nation. Here his knowledge of the building's history and his friendship with the beleaguered owner were of equal importance.

In retirement he continued to research and write with undiminished vigour. What is perhaps his most remarkable book, Architecture and the After-Life, came out in 1991. Here he ranges across the whole of Europe from antiquity to the 19th century and tackles a subject never previously investigated as a whole. Nor is his subject a trivial one - as he remarks in the preface: "Faced with the supreme crisis of death, man has in the past devised elaborate social and religious rituals and has spent enormous sums on sculptured tombs and the buildings to house them." So, for example, Bramante's Tempietto, Henry VII's chapel at Westminster Abbey and the Castle Howard mausoleum all find their place in the book.

Small of stature, quiet of voice, Colvin was not an enthusiastic lecturer. His preference was for conversation, even gossip. In Oxford many a scholar enjoyed his hospitality in college or latterly at home, where he was quite capable of baking a cake for tea.

In 1943 he married Christina Butler, daughter of the professor of Latin at University College London. She predeceased him. He is survived by their two sons.
