Having played 125 times for Croydon Common until they folded in 1916, the goalkeeper joined Arsenal for the 1916/17 season at which time the Great War was well underway.
And it was as a wartime guest for Tottenham when the Football League was suspended that Williamson landed the club in hot water with their north London rivals.
He was in goal for a 2-1 win against Portsmouth on 10 April, 1917, but having not obtained permission from Arsenal to use him, Spurs were fined five guineas, according to the late Tottenham historian Andy Porter.
Then again, with a man like notorious penny pincher Henry Norris running things at Highbury, it's not really surprising. He didn't seem to like Spurs very much and even ensured their relegation from the First Division in 1919.
By all accounts Williamson was a decent goalkeeper, who like so many players at the time, had their promising careers interrupted by war.
Born in 1890 in County Durham, he played for local sides Murton Red Star and Wingate Albion before moving to Southern League side Croydon in 1913. During the war he enlisted in the Footballers' Battalion and then played for the army, as well as guesting for various clubs such as Arsenal and Spurs.
After the conflict he officially became an Arsenal player and made his Football League debut for the club against Newcastle on the opening day of the 1919/20 season, and eventually made 113 appearances for the club. During this time he also played in charity matches for blind war veterans and once got the entire Arsenal team to play against a veterans side in a couple of games in 1920 and 1921 (they were blindfolded).
Williamson, who also played twice for England (below, sixth from the right), left for Norwich in 1922 and retired in 1925. He died in April 1964.
