Griffith was born in Wandsworth, London, and educated at Dulwich College and Pembroke College, Cambridge. He scored over 1,200 runs during four years in the 1st XI at Dulwich, despite being in the shadow of Hugh Bartlett, and he became a capable wicket-keeper. He won his blue in his second year at Cambridge. He toured Australia and New Zealand with the Marylebone Cricket Club under Errol Holmes's captaincy in. He lost his Cambridge place to Paul Gibb in 1937. After graduating from Cambridge, he returned to Dulwich as cricket master and he became the first choice wicket-keeper for Sussex in 1939. He was commissioned into the Officers' Training Corps in 1938, and transferred to the Royal Army Service Corps in 1939. He later served in the Glider Pilot Regiment with Hugh Bartlett. As second-in-command he carried the commander of the 6th Airborne Divisioj, Major-General Richard "Windy" Gale, into Normandy during Operation Overlord, crash landing after being caught in a storm. He took part in the Battle of Arnhem and won the Distinguished Flying Cross. He remained in the Territorial Armyafter the war, reaching the rank of lieutenant colonel. He was appointed captain-secretary of Sussex in 1946. Although he relinquished the captaincy after one year, his wicket-keeping form earned him selection for the MCC tour of the West Indies in 1947–48. On his Test debut he was used as a makeshift opener as three senior batsmen were ill, and made 140 in six hours. It made him the only England player to make his maiden century on his Test debut. He toured South Africa in 1948–49 and played in the final two Tests, the only wicket-keeper to be preferred to Godfrey Evans between 1946 and 1959 when he was available to play. On his return, he retired to take up an appointment as the cricket correspondent of The Sunday Times. After two years in this role, he was appointed by the MCC in 1952 as one of two assistant secretaries to Ronnie Aird at Lord's. He succeeded Aird as the Secretary of the MCC in 1962, and he oversaw the abolition of the amateur status, the introduction of one-day cricket, the creation of the Test and County Cricket Board, the Cricket Council and the 'D'Oliveira Affair'. His busy schedule in 1962–63 prevented him from managing the MCC tour of Australia in 1962–63, except for one month when he flew out to relieve the Duke of Norfolk. Aware of M.J.K. Smith's natural caution on the MCC tour of Australia in 1965–66, Griffith was given extraordinary powers granting him overall control of cricket while managering the tour. Fortunately, he did not resort to these as he preferred more diplomatic means, but he urged attacking cricket in the tour games, notably against Western Australia. Smith asked him when he should declare, Griffith said "Now!" and the MCC won by nine runs in the last minute. The deadpan Smith observed "that's the last time I take the ruddy manager's advice on a declaration". He retired in 1974, and he later served as Chairman of the Friends of Arundel Castle Cricket Club. His son, Mike Griffith, also captained Sussex. Billy Griffith died in Felpham, West Sussex, following a long illness in 1993, aged 78.
