William Fenwick featured during the first season of the recently-renamed Exeter City in 1904/05 and continued to play until the club turned professional in 1908. Working as an accountant, and becoming involved in the club’s administration, he was an important figure in the club’s transition to the professional game as he became a director of the new football company.   

He made his competitive debut for the renamed Exeter City against 112th Battery Royal Artillery on 18  March 1905. A left-back he played in the final four games of 1904/05 ahead of playing in 8 (of 12) games during the following season and 21 in 1906/07. He then added another 18 appearances during City’s final season as an amateur club making his last first-team appearance against Looe on 18 April 1908.

By this time he had been on the committee of the still-amateur Exeter City and, having acted as chairman between 1906 and 1908, became a director of the new Exeter Football and Athletic Company Limited that had been established to bring professional football to the city from 1908.  

William F J Fenwick (born Exeter 1878) is shown as an accounts clerk on the 1911 census for the city. This would suggest he was older than many of the original St Sidwell’s United players and perhaps an example of how another group of players were coming on the scene by 1904. He was recorded as living in Blackboy Road (close to St James’ Park) in 1939 and died in Exeter in 1958 aged around eighty.
