Australian Sydney Cavill (1881–1945), son of the "swimming professor" Frederick Cavill, was 220 yards amateur champion of Australia at the age of 16 and is credited as the originator of the butterfly stroke
所以蝶泳之父应该是澳大利亚人 Sydney Cavill
爬泳嘛,很早就有了,个地方都有人在使用,我们现在看到的这种姿势是经过了很多人的改进,所以没有人可以称为“爬泳之父”。比较近代的使用者是John Arthur Trudgen,他是在南美洲土著学的,自己又做了些改进。
