Teofilo Yldefonso is considered as the finest Filipino swimmer ever. Known as the "Ilocano Shark", Yldefonso is best remembered for accomplishing two feats: being the first Filipino to win an Olympic medal and the only Filipino who won two Olympic medals. He won his first bronze medal at the 200-meter breaststroke event in the 1928 Amsterdam Olympics and his second bronze at the same event in the 1932 Los Angeles Olympics. His fastest time was 2 minutes and 48.4 seconds in the 200-meter breaststroke. Yldefonso was born in Piddig town, Ilocos Norte province.
