Baillie Reynolds was educated a Winchester College, and Hertford College, Oxford. His studies were interrupted by service in the Royal Field Artillery (1915–19) when he served in the 4th West Riding (Howitzer) Brigade. On completion of his studies he became a Pelham Student at the British School at Rome (1921–23). He published Thomas Ashby’s notes on the Castra Peregrinorum as well as a study of the troops based there in the Journal of Roman Studies (1923). In 1923 he was made an award by the Craven Fund to continue his research at the British School at Rome; the other awards were made to William A. Heurtley of Oriel College, and C.A. Ralegh Radford of Exeter College.
In 1924 he was appointed Assistant Master, Winchester College, and later the same year Lecturer in Ancient History, University College of Wales, Aberystwyth (1924–34) where the principal from 1927 to 1934 was (Sir) Henry Stuart-Jones, a former director of the British School at Rome. Baillie Reynolds published The Vigiles of Imperial Rome (Oxford University Press, 1926). From 1926–29 he directed the excavation of the Roman auxiliary fort at Caerhun (Canovium) to the south of Conwy in north Wales; the final report was published by him in 1938. In 1931 he was responsible for excavating the north gate, and in 1932 the west gate of Verulamium as part of the wider project directed by (Sir) Mortimer and Tessa Wheeler. He was elected Fellow of the Society of Antiquaries (1929).
In 1934 he was appointed Inspector of Ancient Monuments for England, Ministry of Works. In 1936 in his capacity as Inspector he supported the proposal to preserve the remains of the Jewry Wall in Leicester that had been excavated by Kathleen Kenyon. In 1935 he was elected to the Council for the Society for the Promotion of Roman Studies, serving alongside Ralegh Radford. In 1947 he was one of the people who helped to acquire the Roman site of Wall from the National Trust.
Baillie Reynolds joined the Royal Field Artillery (TA) (1927–39) while he was in Aberystwyth, and during the Second World War served as a Major in the Royal Artillery (1939–45).
In 1954 he became Chief Inspector of Ancient Monuments, Ministry of Works (1954–1961) replacing B.H. St John O’Neil; A.J. Taylor was appointed Assistant Chief Inspector. One of his projects was the intervention at Corfe Castle in 1959 to stabilise the ruins. Another was the restoration of West Kennet Long Barrow and Wayland’s Smithy; he defended his decisions in The Daily Telegraph (28 July 1962) describing the work as ‘no more a “fake” than is the reconstructed Portland Vase’. In 1960 he advised on the restoration of the Claudian aqueduct that ran through the grounds of the British Embassy in Rome. He retired in 1961 and was succeeded by Taylor.
In 1963 he was elected President, Royal Archaeological Institute (1963–1966) succeeding Ralegh Radford. He was made OBE (1950) and CBE (1957). Baillie Reynolds died in 1973.
