Basil Fulford Lowther Clarke was born on 6 March 1908, the son of the Rev. W. K. L. Clarke.^[1] He was educated at St John's School, Leatherhead and St John's College, Durham.^[1] After Durham he trained to be a priest at Cuddesdon Theological College and was ordained in 1932.^[1] He served as curate at Coulsdon, Monmouth, Watford and Oxford before being appointed Vicar of Knowl Hill, Berkshire, a position he held from 1944 to 1974.^[1]

Clarke and his brother took an early interest in church architecture and were encouraged by their father to record details of any church they visited.^[3] Starting as a schoolboy hobby, during his life he prepared over thirty one handwritten books accompanied by nineteen boxes of documents and postcards from churches he had visited.^[3] He is reputed to have prepared card indexes on two thirds of the 16,000 churches in Great Britain.^[3]

Clarke’s main interest was Victorian church architecture and the gothic revival.^[3] His passion for the genre led him to become a writer of books on the subject and he is notable for his book, Church Builders of the 19th Century, which was published in 1938 when Victorian architecture was somewhat ridiculed.^[7]
