Dooley, born in Sheffield, had the unusual distinction of being a popular figure with supporters of both the northern English city's two major football clubs, having starred for Wednesday as a striker before his playing career was ended prematurely by a broken leg, which later had to be amputated.
After a couple of appearances for Lincoln City, Dooley joined Wednesday in 1947 and became a prolific scorer for the Owls. But in 1953 he broke his leg in a collision during a game and his career was over while his leg was eventually amputated.
He returned to Hillsborough as manager between 1971-73 before being controversially sacked on Christmas Eve 1973. Dooley then joined Sheffield United, initially as commercial manager and carried out a number of backroom roles at Bramall Lane, including that of chairman, before retiring in 2006.
Former British sports minister and ex Blades director Richard Caborn said: "Derek epitomised everything that was good about sport. He was the only person I know who really brought both Sheffield clubs together and was respected by both sets of fans.
"It is a very sad loss for his family, and for football," he concluded.
