3. Tamara and Irina Press, Soviet Olympic Champions
The Press sisters were born in Ukraine in the later 1930s and rose to international track and field stardom in the 1960s. In the 1960 Summer Olympics in Rome, Irina (on left in picture) won gold in the women's 80-meter hurdles and Tamara (right) took silver in the discus and gold in the shotput. In 1964, Irina snagged silver in the hurdles and gold in the first women's pentathlon, while Tamara took first place in both the shotput and discus. All told, the Presses set more than two dozen world records in various events.
In 1966, the European Championships introduced chromosonal testing as a means of checking the gender of competitors. The Soviets withdrew the Presses from that and all future international competitions, which was widely seen as an admission that the sisters were either brothers or the recipients of massive shots of hormone injections.
