The men's horizontal bar was an artistic gymnastics event held as part of the gymnastics programme at the 1904 Summer Olympics. It was the second time the event was held at the Olympics. An unknown number of gymnasts competed, only five are known, all American. The competition was held on Friday, October 28, 1904. Anton Heida and Edward Hennig tied for first, with George Eyser third.
Background
This was the second appearance of the event, which is one of the five apparatus events held every time there were apparatus events at the Summer Olympics (no apparatus events were held in 1900, 1908, 1912, or 1920). Heida was the reigning AAU champion.
Competition format
Each gymnast performed three exercises on the parallel bars, all voluntary in design. Three judges each gave scores from 0 to 5 for each exercise; thus, the maximum for an exercise was 15 and the maximum total was 45.
