If the caption for this February 29, 1920 newspaper photo can be believed, Charles Durborow (also spelled, Durborrow, Durboro, and even Durbonard) took a plunge every day!
The caption for this photo reads:
Charlie Durborrow, Philadelphia’s famous bank clerk long distance swimmer, just has to have his daily dip in the Delaware at Riverton, N.J., regardless of where the mercury happens to be. Here he is playing the new game of ice polo all by his lonesome.
