In 1896 began swimming as Olympic sport, and is since never been off the program. The very first Olympic swimmatches were swum in the Bay of Zea (near Piraeus, the haven of Athene). The water was very cold, whereby swimmers who used to swim in warm water swam slower. In 1900 were the swimmatches in the Seine, in 1904 in an artificial lake and in 1906 again in open sea. In 1908 was there a indoor swimming-pool of 100m. In 1924 was there for the first time a swimpool of 50m.
In 1928 won Martha Norelius (USA) the gold medal by the 400m free stroke, just as in 1924 (official, she was Swedish). Her father had already won a gold medal in 1912 as member of the Swedish swimteam, and later she married with the Canadian rower Joseph Wright (who won silver in 1928).
Loser is faster?
In 1984 there were two strange incidents. Carrie Steinseifer (USA) and Nancy Hogshead (USA) won a gold medal on the 100 m free stroke (same time).
In the B-final, swam the winner a new Olympic Record. And the winner of the A-final swam slower than he! That is fed up.
By the Olympics in 1912 missed 3 best swimmers of USA the semi-final 100 m. Someone had told them that there no semi-final should been swum.
