The son of James Fezard Walker and his wife, Ethel, he was born in
Wandsworth in August 1912. He was educated at
King's College School in
Wimbledon, London. Walker was later approached by
Hampshire, who persuaded him to pursue a career as a professional cricketer. Walker made 24 first-class appearances in his debut season, scoring 930 runs at an
average of 25.83; he scored his maiden
century during the season against
Sussex at
Portsmouth, when he made 123 runs; this innings was notable for it formed part of a 235 runs partnership for the fifth wicket with
Gerry Hill (161 runs), The following season, Walker made 23 first-class appearances, scoring 925 runs at an average of 23.71, though he did not record any centuries. The outbreak of the
Second World War at the beginning of September 1939 bought first-class cricket, and unbeknownst to Walker, his cricket career to an abrupt end. Described by
Wisden as "sound in defence, with unlimited patience" who demonstrated "good strokes all round the wicket", A capable fielder who occasionally
kept-wicket, he took 75 catches. Alongside playing cricket, Walker played
rugby union, he captained the
Dorset county team, and also captained a
Royal Air Force side during the war. ==WWII service and death==
