Jesse Owens
Owens's greatest achievement came in a span of 45 minutes on May 25, 1935 at the Big Ten meet in Ann Arbor, Michigan, where he set four world records. He tied the world record for the 100 yard (91 m) dash (9.4 seconds) and set world records in the long jump (26 feet 8¼ inches (8.13 m), a world record that would last 25 years), 220 yard (201 m) dash (20.3 seconds), and the 220 yard low hurdles (22.6 seconds to become the first person to break 23 seconds). This incredible feat is widely considered one of the most amazing athletic achievements of all time.  In fact, in 2005 both NBC sports announcer, Bob Costas, and University of Central Florida Professor of Sports History, Richard C. Crepeau chose this as the most impressive athletic achievement since 1850.
