David Armbruster and Jack Sieg, a coach and his swimmer, both a part of the University of Iowa swimming and diving team, helped to develop the fourth type of stroke that we know today. Armbruster only saw the breaststroke as a slow caterpillar, and figured there could be a way to make the breaststroke faster. Armbruster improved the arms, while Sieg had the kick, and together they were able to form the butterfly stroke. There was one slight problem however, the stroke was illegal in competition at the time. The mere caterpillar was still stuck in it's cocoon. With a great deal of convincing, and a long 20 years, the caterpillar was eventually able to morph into a beautiful butterfly, and the University of Iowa became known as the home of the butterfly stroke.
