Nottinghamshire and educated at
Wesley College, Sheffield. He trained in architecture under
William Botterill from 1873 to 1877, and joined the practice as a partner in 1881. After Botterill's son's early death in 1879 Bilson became the main partner in the practice, and took over the business completely when Botterill retired in 1899. on his work at Durham it has been written
"The chronology of the works [..] of construction have been established by John Bilson on such solid bases that there is nothing significant to be added." John Bilson also wrote an article for the 1911 Encyclopædia Britannica on
Romanesque and Gothic Architecture in England. Photographs attributed to Bilson are held by The Courtauld in the Conway Library of art and architecture, and are currently being digitised. ==References==
