Waddell, who also played 18 times for Scotland over a five-year period up to 1962, remains the only Scottish fly-half to have become a double Lion.
Injury and university examinations prevented him from playing more often on his first Lions adventure but he was hugely impressive when he did feature, scoring seven tries in just 10 games on the New Zealand leg of the 1959 tour.
Waddell's second Lions tour was to South Africa - a country to which he would eventually emigrate - and it was here that he made both his Test appearances for the visitors.
He was selected for the first and second games of the four-match rubber with the Springboks, with the Lions drawing the opener before losing the follow up 3-0.
Although not as prolific a try scorer as on his first Lions adventure, Waddell did claim a brace of tries and kick a conversion and four drop goals in the land he would later call home.
Born on April 12 1937, Waddell was the son of 1924 Lions tourist Herbert Waddell who was also the president of the Barbarians.
Gordon followed in his father's footsteps by playing 12 times for the Baa-Baas, while he also won three Blues during his time at Cambridge University.
He added an MBA at Stanford University to his undergraduate degree at Cambridge and also served as a Royal Marine Commando.
After making his Scotland debut in 1957, Waddell captained his country on five occasions and was the most-capped Scottish fly-half until John Rutherford broke his record in the 1980s.
He added to his success on the field with a comprehensive business career, boasting spells as a director of E. Oppenheimer & Son Ltd, chairman of Johannesburg Consolidated Investments and director of Cadbury Schweppes among his considerable achievements.
He also spent time as a politician for the Progressive Party in South Africa having been elected as a Member of Parliament for Johannesburg North in 1974.
Waddell died on August 13 and leaves behind his wife Kathy and five children.
