Ethel Scott (1907–84) had a Jamaican father and an English mother was the first black woman to represent Great Britain in an international athletics competition. She was a sprinter active in international competitions for a brief period in the 1930s. In general, Scott's achievements are only thinly documented, and she is largely unknown to the British public and historians of sport. Jamaican-born Tessa Sanderson became the first British African-Caribbean woman to win Olympic gold, receiving the medal for her javelin performance in the 1984 Los Angeles Olympics. Denise Lewis, of Jamaican heritage, won heptathlon gold in the 2000 Sydney Olympics, a games where 13 of Britain's 18 track and field representatives had Afro-Caribbean roots. Four years later in the Athens Olympics, Kelly Holmes, the daughter of a Jamaican-born car mechanic, achieved the rare feat of taking gold in both the 800 and 1500 metres races. In the same games, Britain's men's 4 × 100-metre relay team of Marlon Devonish, Darren Campbell, Mark Lewis-Francis and Jason Gardener, all of African-Caribbean heritage, beat the favoured United States quartet to claim Olympic gold.
