Glenn Hardin
Hardin's rise began at the 1932 Summer Olympics , where he finished second in the 400 m hurdles in 52 . 0 but was given credit for a world record when the winner , Bob Tisdall from Ireland , knocked down a hurdle , an error that in those days disqualified a performance for world record consideration .
