(The inaugural&amp;nbsp;Indianapolis 500&amp;nbsp;was not held until two years later, in 1911.) Medical, sports and social history began unfolding lickety-split at the world-famous racetrack. Hoosier History Live will explore the eras involving the Speedway’s first three chief medical officers, a 50-year span ending in 1959.&amp;nbsp; Helmets for Indy 500 drivers did not become mandatory until the mid-1930s. The first chief medical officer was overruled in 1914 when he disqualified a driver who had visual challenges. And the second chief medical officer resigned in 1951 when a beer tent was erected at the racetrack, saying he did not want to have to treat “drunks”.
