At the 1964 Olympics, Claudia Kolb, a 14-year-old from the Santa Clara SC, won an unexpected silver medal in the 200m breaststroke. She had only made the Tokyo final as the fifth fastest qualifier, but a brilliant finish took her from fourth to second place in the last 25 meters. After the 1964 Olympics, Kolb concentrated on the individual medley and set the inaugural official world record at 200m in 1966. At the Mexico Olympics she won both individual medley events by incredible margins, and during her six-year career she set a total of 23 world records. In all she won 25 AAU titles and at the 1967 Pan-American Games she won both individual medley events and the 200m butterfly in addition to placing second in the 200m breaststroke.
