Born in Birmingham, Camkin was appointed honorary managing-director of the football club in September 1939, and when W. H. Grady died in 1941, took over secretarial duties in addition. Team manager George Liddell had resigned on the outbreak of war, and Camkin, together with trainerGeorge Blackburn, oversaw team affairs until November 1944, when Ted Goodier took over as caretaker manager. Although the Football League was suspended for the duration of hostilities, Birmingham competed in regional league and cup matches. Camkin remained on the club's board of directors until ill-health forced his retirement in 1951, when he was elected as vice-president of the club. He died at his home in Leamington, Warwickshire in April 1956 aged about 66.
His son John Camkin, a journalist and broadcaster, who lived in Leamington Spa served on the board of Coventry City and was secretary of the League Managers Association. In the 1970s he owned a string of travel agencies (Camkin Travel) in the Midlands that were eventually sold to the Lunn Poly/Thomson Group.
