John Ulick Knatchbull, 7th Baron Brabourne, CBE (9 November 1924 – 23 September 2005), professionally known as John Brabourne, was a British peer, television producer and Oscar-nominated film producer. Married to a daughter of the 1st Earl Mountbatten, Brabourne was a survivor of the bombing which killed his father-in-law.
Brabourne was born in 1924, the second son of Michael Knatchbull, 5th Baron Brabourne and his wife, Lady Doreen Knatchbull. He was educated at Eton College and Brasenose College, Oxford. He was hardly 14 when his father died in February 1939 and his elder brother, Norton, inherited the Barony.
The Second World War broke out just as Brabourne was finishing school, and he enlisted in the armed forces. He served in the Coldstream Guards, rising to the rank of Captain. He fought in France from 1943 onwards. In 1943, his elder brother, Norton, a Lieutenant in the Grenadier Guards, was wounded and captured in Italy. While being transported to Germany as a POW, he tried escape, but was captured and executed by the SS on 15 September 1943. Since he died childless, his barony passed to his younger brother, John Knatchbull, who became the 7th Lord Brabourne.
