Lygon was born on 22 February 1912, the daughter of
William Lygon, 7th Earl Beauchamp and Lady Lettice Grosvenor, daughter of
Victor Grosvenor, Earl Grosvenor and granddaughter of
the 1st Duke of Westminster. Her friendship with
Evelyn Waugh began in the early 1930s. To Lygon, Waugh explained that the Lygons were only part of inspiration for the novel
Brideshead Revisited; Dorothy most likely inspired the character of Lady Cordelia Flyte. According to Laura ( Herbert), Waugh's wife, Dorothy was "the nicest of all" her husband's friends. Waugh dedicated
Black Mischief to Mary and Dorothy Lygon. During
World War II, Lygon served as a Flight Officer in the
Women's Auxiliary Air Force posted to Italy. After the war she moved to a farm in Gloucestershire. In the 1950s, she worked as social secretary at the British Embassy in Athens. In 1956, she moved to Istanbul, working as a governess. She then moved to the
Hydra. In the 1960s she moved back to England and worked as an archivist at
Christie's. They "parted amicably" a year later. She was instrumental in re-publishing in 2000 the lost work
The Girls of Radcliff Hall. She died in 2001, aged 89. ==References==
