Colonel Sir Michael Picton Ansell, CBE, DSO (26 March 1905 – 17 February 1994) was a soldier, showjumper, polo player, and horse show administrator.

Ansell was born on 26 March 1905 at the Curragh, County Kildare.^[1] His father Lt Col George Ansell was killed in September 1914, during the First World War, leading the 5th Dragoon Guards in a cavalry charge against German positions, for which he was subsequently mentioned in dispatches.^{[2] [3]} After attending St Michael's Westgate-in-Sea and Wellington College he went to Royal Military College, Sandhurst.

In August 1924 he was commissioned into the 5th/6th Dragoons, a regiment formed two years earlier by the amalgamation of the 5th Dragoon Guards and 6th (Inniskilling) Dragoons (his father having served in both regiments). He served throughout the 1930s a cavalry officer, show jumping rider,^[1] and international polo player.

In France in March 1940, during World War II, he was given command of a yeomanry regiment, the 1st Lothians and Border Horse, becoming the British Army's youngest commanding officer at the time.^[1] He won the Distinguished Service Order (DSO), but was shortly afterwards wounded in the hand and eyes by "friendly fire", blinding him permanently, and then became a prisoner of war (POW).^[1] All four fingers on his injured left hand were later amputated.^[4] He was repatriated from a German POW camp in 1943.^[1]

From 1957 to 1962 he was Colonel of the 5th Royal Inniskilling Dragoon Guards.^[5]

An invitation to take up the position of chairman of the British Showjumping Association led to him being credited with revitalising the sport.^[1] He restarted the Royal International Horse Show and initiated the Horse of the Year Show.^[1] He was Chairman of the British Horse Society^[6] and Chaired the British Showjumping Association from 1945 until 1964.^[4] He was the first president of the British Equestrian Federation.^[6]
