Addenbrooke was one of the founding members of Wolverhampton Wanderers (as St. Lukes F.C.) in 1877 while working as a teacher at St. Luke's School in Blakenhall. He moved to Saltley College in Birmingham, but in 1883 joined Wolves as a player, playing as a forward in their reserve side, but never making a first team appearance.
In August 1885 he was appointed as Wolves' first-ever paid secretary-manager, guiding the side to FA Cup wins in 1893 and 1908 and runners-up in 1889, 1896 and 1921. He was awarded a Football League long-service medal in 1909.
He took leave from the club in June 1922 due to ill health and died just months later. His 37-year term as manager of Wolves remains the longest in club history.
