The native of Winnipeg was born in 1914, the son of Percy Harold Nicklin and Eva Louise Nicklin.[1][2] He played Canadian football as a back with the Winnipeg Blue Bombers from 1934 to 1940.[3] In 1935, Winnipeg became the first Western team to capture the Grey Cup. While Nicklin was there, the club advanced to the Grey Cup twice more in 1937 and 1938, before losing in the finals.[4] In 1939, Winnipeg returned to capture the 27th Grey Cup by defeating the Ottawa Rough Riders.[5] Nicklin received Western all-star honours as an end in 1937 and 1938, and as flying wing in 1939.[4]
He also played in the Tea Bowl for the Canadian Army football team against American Army team at White City Stadium on February 13, 1944 in London, England (the Canadians won 16-6, and Nicklin scored the final touchdown).[6]
On D-Day, June 6, 1944, he landed in the midst of a German position at Varaville. His parachute was ensnared on a rooftop, and he received fire from German soldiers before he cut himself free and took cover.[5] He eventually rejoined his unit, and was later wounded by shrapnel.[5][7]
He was killed in action on March 24, 1945.[5] During an airborne assault across the Rhine northwest of Wesel as part of Operation Varsity, Nicklin's parachute became tangled in a tall tree, and as he attempted to free himself, he was shot and killed by German soldiers.[1] He is now buried in Groesbeek Canadian War Cemetery. He left a widow, Mary Eileen Nicklin, in Port Credit, Ontario.[2] On July 12, 1945 it was announced that he had been appointed Officer of the Order of the British Empire, "in recognition of gallant and distinguished services in North-West Europe (to be dated the 30th June, 1945)".[8] The original recommendation for the honour describes how he was able to "rectify certain aspects of the Battalion's life which were not satisfactory" and credited him with "the smooth working and unparalleled success which has met the inclusion of a Canadian Battalion in a British Brigade", the recommendation concludes, "throughout the present campaign his example of courageous leadership has been an example to all who have come into contact with him."[7]
A documentary film about Nicklin, Jeff Nicklin: Hero of the Gridiron and the Battlefield, has been produced by the War Amps of Canada.
Nicklin's story and that of the 1st Canadian Parachute Battalion during Operation Varsity was featured in the episode "Across the Rhine - Paratroopers in Germany" of Season 1 of the documentary series War Story.
