Lieutenant colonel Alan Key (4 June 1908 – 2 July 1989) was a British Army officer and England international rugby union player of the 1930s.
Born in Amersham, Buckinghamshire, Key was educated at Cranleigh School in Surrey, where he gained his blues as a stand-off, before becoming a scrum-half for Old Cranleighans. He has the distinction of being first Old Cranleighan to be capped for England and ascended to the club captaincy in 1933.[1]
Key was versatile enough to play in every backline position except fullback in matches for the Barbarians, though he was best suited to scrum-half.[2] He was a Middlesex representative player and gained two England caps, against Ireland at Lansdowne Road in the 1930 Five Nations and Wales at Twickenham in the 1933 Home Nations.[3]
