From 1926 he taught history at the Victoria University of Manchester, first as an Assistant Lecturer and then as the Bishop Fraser Lecturer. At Manchester he worked under F. M. Powicke, Professor of Mediaeval History, who influenced Pantin's work for the rest of his life.[1] In 1929 the Royal Historical Society awarded its Alexander Prize to Pantin for his essay The General and Provincial Chapters of the English Black Monks, 1215–1540.[1] The "Black Monks" were the Order of Saint Benedict, whose history in England remained a subject of Pantin's research and published works for the rest of his life.[1]
Pantin was active in the Oxford Architectural and Historical Society (OAHS), serving on the Editorial Committee of its journal Oxoniensia and on the OAHS's Sub-Committee for Old Houses.[3] He was President of the OAHS 1959–64.[3]
During his career at Oxford a substantial number of the city's unique mediaeval buildings were destroyed for redevelopment. In 1936–37 the University of Oxford had a row of historic houses in Broad Street demolished to make way for the New Bodleian Library.[4] In 1954–55 F. W. Woolworth had the mediaeval Clarendon Hotel in Cornmarket Street demolished to make way for a new retail store.[5] In 1959 Oxford City Council had Lower Fisher Row beside Castle Mill Stream demolished as slum clearance.[6] In each case Pantin recorded the buildings as fully as possible before and during their demolition, and published his results in Oxoniensia.[4][5][6]
Pantin retired from his college and university posts in 1969, and Oriel College made him an Honorary Fellow in 1971.[7] He died on 10 November 1973.[3]
