Australian Elizabeth "Betty" Cuthbert won two gold medals in the individual track sprints (100 and 200 metres) and
a third gold in the 400 metre relay in at the 1956 Melbourne Olympics. The 18-year-old was instantly acclaimed as a
national heroine by the home Australian crowd, and was nicknamed the "Golden Girl". Injury prevented her from
doing well at the 1960 Games but she came back to win the 400 metres in 1964 at Tokyo and claim her fourth
Olympic gold medal, which she regarded as her greatest win. She is the only Olympic sprinter, man or woman, to have
won gold medals in the 100 metres, 200 metres, and 400 metres. At the British Empire and Commonwealth Games
she won a gold medal in the 4×110 yards relay (with [Joyce Bennett] and the non-Olympians Brenda Cox and Glenys
Beasley) in 1962 and silver medals in the 220 yards as well as in the 4×110 yards relay (with [Marlene
Mathews-Willard] and the non-Olympians Kay Johnson and Wendy Hayes) in 1958. In the 1958 British Empire and
Commonwealth Games 100 yards Cuthbert finished fourth and in the 1962 British Empire and Commonwealth
Games 220 yards she finished fifth, but in the 100 yards she was eliminated in the semi-finals. She set or equalled
18 world records between 1956 and 1964 over 60 metres, 100 yards, 220 yards, 400 metres, and in the 4×100 and
4×220 relays. In 1964 she was awarded the prestigious Helms Award for her contributions to sport. Sadly for such a
fine athlete, she later was afflicted with multiple sclerosis, having first been diagnosed with that disease in 1979.
At the 2000 Sydney Olympics, aided by a wheelchair, she was one of several Australian women who carried the
Olympic Flag at the Opening Ceremony.
Personal Bests: 100 – 11.4 (1956); 200 – 23.1y (1960); 400 – 52.01 (1964).
