Heather Seymour "Judy" Guinness (14 August 1910 – 24 October 1952) was a British fencer. She won a silver medal in the women's individual foil event at the 1932 Summer Olympics.[1] [2] The judges had awarded her the gold medal but, in a noted gesture of fair play, she informed them they had failed to count two hits achieved by her Austrian opponent Ellen Preis.[3]
She was a daughter of Henry Guinness (d.1945), an Irish engineer, banker and politician. In 1934 she married the racing driver Clifton Penn-Hughes. He died in a plane crash and she remarried John Henning in 1942. She died in 1952 at Springhare Farm in Rhodesia.[2]
