In 1933, Henry Myers swam a butterfly stroke in competition at the Brooklyn Central YMCA. The butterfly style evolved from the breaststroke. David Armbruster, swimming coach at the University of Iowa, researched the breaststroke, especially considering the problem of drag due to the underwater recovery. In 1934 Armbruster refined a method to bring the arms forward over the water in a breaststroke. He called this style "butterfly".
