At the 1904 Summer Olympics, a water polo tournament was contested, with three club teams of seven players each.

[1] A German team tried to enter, but its entry was refused because their players did not play for the same club.

[2] The event took place in an artificial lake in Forest Park, the location of both the Olympics and the World's Fair.

[3] Two of the Olympians died of typhoid fever soon after the competition, possibly from contamination caused by livestock at the opposite end of the lake.
