Casson was a native of Burnley, Lancashire.

The Burnley News of 3 May 1919 reported, Burnley Double Medallist. On Thursday afternoon, in the Mayor's Parlour at Burnley Town Hall, two military decorations were presented to Mr. J. Casson, 8, Junction Street, Burnley, formerly a Private in the 9th East Lancashire Regiment, and now employed as a driver on the Burnley Corporation Tramways. Mr. Casson enlisted in September 1914, prior to which he was on the tramways. The decorations, which were the Military Medal and the Greek Medal, were awarded for gallantry in rescue work during the Salonika operations. As a further tribute, members of the Tramways Committee were present. In presenting the awards to the recipient, the Mayor said the people of Burnley would feel proud to know that one of their townsmen had been honoured by two countries, and he hoped Driver Casson would appreciate them, not for their intrinsic value, but for the manner in which they had been won. The occasion on which the awards were gained was during the operations which resulted in the smashing up of the Bulgarians, and Driver Casson had shown grit, determination, and pluck in winning them. Briefly responding, Driver Casson said he had the satisfaction of knowing there was a man living that day who would not have been living but for his actions. The Burnley Express also reported the presentations but included a paragraph stating, "He went out to France in 1915, but after ten weeks was transferred to the Salonika front were he served for three years, during which time he won the Greek Military Cross and the British Military Medal. His mother lives at 3, Beech Street, Padiham. One of his brothers is discharged from the Army; and his brother Richard, who was formerly a clerk in the Burnley Post Office, is still serving with the Royal Engineers."
