From the DND / RCAF website:  Wing Commander John “Moose” Fulton, D.F.C., A.F.C., photographed on June 12, 1942, was the first commanding officer of 419 Squadron. He died on July 29, 1942, at the age of 29, and his name is engraved on the Runnymede Memorial in the United Kingdom, which records the name of airmen who have no known grave.

I learned the story of “Moose” Fulton today on the Royal Canadian Air Force website, in a story about a recent reunion of his 419 Squadron in Kamloops, BC.  419 Squadron was part of the British Commonwealth Air Training Plan, and prepared fighter pilots for combat.  To this day, it is named after it’s first commander.
419 “City of Kamloops” Squadron was named in honour of their beloved first commanding officer, John “Moose” Fulton, who grew up in Kamloops and from whom the squadron personnel received their designation as the “Moosemen”. 419 Squadron, whose unit badge portrays a charging moose, is reputedly the only Canadian squadron named after a person. And to this day, all 419 Squadron commanding officers retire their own call signs for the duration of their command and take the call sign “Moose” in honour of “Moose” Fulton. 
A very touching montage of photographs, including the only surviving member of 419 Squadron from World War Two, may be found here.
