Howard Millar Nixon was born in Westminster on 3 September 1909 to Leigh Hunter Nixon, a minor canon and precentor of Westminster Abbey, and Harrie Nixon. He accordingly was raised in the Abbey precincts. Nixon was educated at Marlborough College before studying at Keble College, Oxford, where he took a degree in history in 1931. After graduating and finding employment hard to come by, he took up his father's suggestion of working in the Abbey's library, a task that Nixon enjoyed sufficiently to study for a diploma at the School of Library Studies at University College London. In 1936 he began work as a temporary assistant cataloguer at the British Museum; he would eventually rise to the positions of Assistant Keeper in 1946, Deputy Keeper in 1959, and head of rare book collections in 1966. His career was interrupted by war service when he was called up as a major in the Royal Artillery during the Second World War. He spent this time visiting anti-aircraft sites across the country, visiting many local libraries in the process. In 1951 Nixon married Enid Bromley with whom he had three sons. Returning to the British Museum, Nixon was involved in setting up a microfilm unit and also developed an interest in bookbinding history, a subject upon which he published extensively. In his obituary, The Times called him the "doyen of historians of bookbinding in Britain", with a "keen eye" for detail who had given the subject "not merely an academic distinction that it had lacked before but also a basis on which others will build with confidence". On retiring from the British Museum, Nixon became Librarian of Westminster Abbey in 1974, and held the post until his death. He was appointed Lecturer in Bibliography at the School of Library Studies at University College London in 1959, holding the post until 1976; he was also Sandars Reader in Bibliography at the University of Cambridge from 1967 to 1968 and Lyell Lecturer in Bibliography at the University of Oxford from 1978 to 1979. Nixon served as president of the Bibliographical Society from 1974 to 1975 and was awarded the society's gold medal in 1978. He was appointed an Officer of the Order of the British Empire in 1983 and was elected to an Honorary Fellowship of Keble. Nixon died on 18 February 1983. His remains are buried in the east cloister of Westminster Abbey.
