# Swimming at the 1912 Summer Olympics – Men's 400 metre breaststroke

The men's 400 metre breaststroke was a swimming event held as part of the swimming competition at the 1912 Summer Olympics. It was the second appearance of the event, which had been introduced (as the 440 yard breaststroke) in 1904. The competition was held from Monday July 8, 1912 to Friday July 12, 1912.
Seventeen swimmers from ten nations competed.
The final of the event was a rematch of the five swimmers who had competed in the final of the 200 metre race. Bathe won once again (and indeed, set a new Olympic record each time he raced in both breaststroke events), with Henning providing a stiff challenge in the semifinals. Neither Lützow nor Malisch were able to medal in the longer race, as Henning took silver and Courtman finished third.
