Tranmere Rovers Football Club are an English team founded in 1884, and based in Birkenhead, Wirral. As of the end of the 2014–15 season, the club has had 28 managers. The first man to hold this position was Bert Cooke, appointed in 1912. He oversaw the club's entry into the Football League and remained in charge for 23 years, the longest spell of any manager at the club. Major changes were not seen until businessman Dave Russell took over in 1961. His introductions included the team's current all-white kit and regularly arranged floodlit home fixtures on Friday evenings rather than the usual Saturday afternoon.
