James Maher Rosenberger, Irish American track and field athlete and a member of the Irish American Athletic Club is born in New York City on April 6, 1887.

In 1909, at the Amateur Athletic Union (AAU) metropolitan senior championships, held at Travers Island, New York, Rosenberger takes first place in the 100- and 220-yard dash. The following week, he is part of the Irish American Athletic Club’s four-man relay team that breaks the world record for the one-mile relay with a time of 3 minutes, 20 2/5 seconds. The other three men on the record-breaking team are C. S. Cassara, Melvin Sheppard, and William Robbins.

On April 9, 1911, Rosenberger anchors the Irish American Athletic Club 4×440-yard relay team that breaks the world record at Celtic Park, Queens, New York City and sets the first International Amateur Athletic Federation– recognized world record for 4×440-yard or 4×400-meter relay race, in time of 3 minutes and 18.2 seconds. The other members of the world record-setting team are Harry Gissing, Melvin Sheppard and Harry Schaaf.

Rosenberger participates in the 1912 Summer Olympics in Stockholm but is eliminated in a 400 metres semifinal. The following year he competes in Australia with the AAU team, and in 1915, he becomes the coach for the Long Island Athletic Club.

Following his retirement from track and field, Rosenberger later works as an auditor and is a track coach at St. John’s University.

Rosenberger dies in Brooklyn, New York, on January 1, 1946. He is buried at Calvary Cemetery, Woodside, Queens, New York.
