Today in sports history

Fifty years ago today (and yesterday), 15-year-old Australian swimmer John Konrads set six world records in two days. Konrads would set 26 world records during his swimming career, but only won one Olympic gold medal, in the 1500-meter freestyle in 1960 in Rome (that's him in the middle of that photo, after winning said medal).

The Latvian-born Konrads and his sister Ilsa, who also set multiple world records in swimming, were known as the Konrad Kids in the '60s.
