Joseph Boyer Jr. (May 30, 1890 – September 2, 1924) was an American racing driver, and a winner of the 1924 Indianapolis 500.

Early life

Boyer was born on May 30, 1890, in St. Louis, Missouri and grew up in Detroit, Michigan, the son of Joe Boyer Senior and Clara Libby. He became wealthy due to his father owning Burroughs Adding Machine Company and Chicago Numatic.

Racing career

At the 1924 Indianapolis 500, Boyer participated in two different cars during the race. In his original entry (#9), he qualified 4th. Boyer experienced mechanical troubles, and on the 109th lap he was given relief. His relief driver went on to race that car until lap 176, when he crashed in Turn 1. On lap 111, Boyer took over car #15 from L. L. Corum. Boyer charged to the front of the field, and led the last 24 laps in Corum's car. Corum and Boyer were scored as "co-winners," the first time in Indianapolis 500 history such a designation had been assigned. In three previous Indianapolis 500s (1911, 1912, 1923), a winning driver had been given relief help during the race, qualifying, starting, and finishing in the same car. 1924 was the first time one driver relieved another entirely, and had gone on to win.

Death

Boyer died on September 2, 1924, from injuries sustained in a crash at Altoona Speedway in Tyrone, Pennsylvania the day before.
