Gordon Herbert Waddell (12 April 1937 – 13 August 2012, in Glasgow) was a Scottish rugby union player, a South African politician, and the son of Herbert Waddell. He played for Scotland, the Barbarians and on two British and Irish Lions tours. In fact he is the only Scottish stand off to be a double lion. He had 18 caps between 1957–62 - this record for a Scotland fly-half was only later broken by John Rutherford. He played 12 times for the Barbarians between 1957 and 1960, scoring in three matches including their 1958 match against East Africa in Nairobi on 28 May 1958. In 1962 he was the controlling influence in Scotland's first win in Wales since the 1930s, a feat not repeated for another twenty years.
Waddell was educated at St. Mary's School, Melrose and Fettes College, Edinburgh before attending Cambridge University (BA). Waddell also obtained an MBA from Stanford University.
Between 1958 and 1961 Waddell won 3 blues for Cambridge at Fly Half. The 1961 Cambridge side is considered one of the finest ever Varsity Match sides and they are still to this day the only unbeaten Varsity XV in history-).
Waddell was selected in his first year out of school while doing National Service, where he became a Royal Marine Commando, to play rugby for Devonport Services and the Royal Navy including the Calcutta Cup game in 1957. Between 1957 and 1962 Waddell won 18 caps for Scotland, 5 of which he won as Captain including the Test Match against South Africa in Port Elizabeth in 1960. In 1962 he was the controlling influence in Scotland's first win in Wales since the 1930s, a feat not repeated for another twenty years. During his 18 caps he was never dropped, although he had to leave because of injury - this record for a Scotland fly-half was only later broken by John Rutherford. Waddell and his father Herbert Waddell are one of the very few examples of a father and son having played for the same teams in the same position. Both were Fly Halves for Scotland and the British Lions.
