The development of swimming
      1912 - 1932        

« The instictive thing for a beginner to do is to hold his breath. As soon as he learns to overcome this, half his fight is won, and he is ready for the finer points of swimming. »

« After improving my breath control, …, where a mile a day had exhausted me completely, I began to do a mile and a half a day with greater ease »

Weissmuller, 1930
