Matt Cowdrey

Cowdrey, born without most of his left arm, swam in the S9 class and won 13 Paralympic golds and 23 medals from Athens 2004 to London 2012, Australia's most successful Paralympian. S9 is among the most competitive classes because the impairments are relatively mild, so his long run of freestyle and medley wins, often in world records, is especially strong. He later became a politician in South Australia.
