What was the evolution on the men's 100m sprint world record in the Olympics?

Answer 1

1900 Frank Jarvis and Walter Tewksbury equalled the world record at 10.8 (the record first set in 1891) in the trials and semi-final. This before the existence of the IAAF as the world wide governing body.

1912 David Lippincott established the first IAAF world record at 10.6 in the heats. The unofficial record at the time was 10.5

1920 Charlie Paddock equalled the Lippincott record in the final

1932 Eddie Tolan and Ralph Metcalfe equalled the world record of 10.3

1964 Bob Hayes equalled the world record of 10.0

1968 Jim Hines equalled the hand timed world record of 9.9 His automatically timed 9.95 was later accepted as the first auto-timed world record

1988 Ben Johnson broke his own world record at 9.79. At the meet he was caught with Performance Enhancing Drugs in his system and was disqualified, along with erasing his previous world record of 9.83. Second place in that race, Carl Lewis was awarded both the gold medal and the world record at 9.92 while Johnson was banned for life from the sport.

1996 Donovan Bailey set the world record at 9.84 while winning the gold medal.

2008 Usain Bolt set the world record at 9.69 while winning the gold medal.

Around all these records, obviously other world records were established in different meets.
