The 100-yard backstroke was contested by six swimmers, three American and three Germans. The Americans were no contest at all for the Germans who dominated the backstroke and breaststroke events in this era. The Germans swept the medals, led by Walter Brack who finished in 1:16.8 followed by Georg Hoffmann, and Georg Zacharias.
