As a "Number 8" he played international rugby for Wales and club rugby for Cambridge University, Edinburgh Wanderers, Gloucester, Newport, London Welsh, Llanelli and Wasps. Gwilliam played in his first international game on 20 December 1947 against Australia. His last international game was against England on 16 January 1954.
In 2005 he was inducted into the Welsh Sports Hall of Fame.
Gwilliam was born in Pontypridd, the son of Thomas Albert and Adela Audrey Gwilliam. He attended Monmouth School and went up to Trinity College, Cambridge in 1941.
After spending a year at Cambridge, he was commissioned as an officer in the Royal Tank Regiment and saw action in Europe. The historian Max Hastings reports an incident at Rathau where Gwilliam was carrying a small German soldier by the scruff of his neck.
Asked why he didn"t just shoot the man, Gwilliam purportedly replied "Oh no sir.
Much too small". After the war, he returned to Cambridge and then became a schoolmaster. He taught at Glenalmond College, Perth 1949-1952, at Bromsgrove School 1952-1956, as Head of Lower School at Dulwich College 1956-1963 and eventually as Headmaster of Birkenhead School from 1963–1988, where he is remembered for his disciplinary standards and his religious views.
He was described "as physically imposing, quietly spoken, religious and austere - the phrase "Cromwellian" tends to recur in descriptions."
He lives in retirement at Llanfairfechan, Gwynedd.
He is related to West Ham United and Wales midfielder Jack Collison.
