Carl Lewis won both the men's 100 metres and 200 metres at the 1984 Los Angeles Olympics.
Lewis also won the long jump and anchored the United States to victory in the 4 × 100 metres relay. His four gold medals matched Jesse Owens's achievement at the 1936 Berlin Games, making Lewis one of the defining stars of the Los Angeles Olympics.
Lewis won the 100 metres in 9.99 seconds and the 200 metres in 19.80 seconds. He became the first athlete since Owens to win four athletics gold medals at one Olympic Games, a feat that attracted worldwide attention.
The achievement is sometimes confused with Usain Bolt's later Olympic sprint double. Bolt won the 100 and 200 metres at three consecutive Games, but Lewis's 1984 performance included two additional athletics titles.
