Synchronised swimming is a relatively new discipline that has its origins in water acrobatics. It is hugely popular in the United States.
Glass tank performer
At the turn of the 20th century, Annette Kellerman, an Australian swimmer, toured the United States performing water acrobatics. Her shows proved very popular and a sport was born.
Performing with music
The sport was developed further by Katherine Curtis, who had the idea of combining water acrobatics with music. Her students performed at the 1933-34 Chicago "Century of Progress" Fair, where the announcer, former Olympic swimming gold medallist Norman Ross, coined the term "synchronised swimming".
Synchronised swimming was later popularised by American film star Esther Williams, who performed water ballet in several American movies. The competitive aspect was developed around the same time when Frank Havlicek, a student of Katherine Curtis, drew up a set of rules.
A relatively recent discipline, synchronised swimming became an Olympic sport for the first time in Los Angeles in 1984, with solo and duet events. These events also took place at the Olympic Games in 1988 in Seoul and in 1992 in Barcelona. Atlanta replaced them in 1996 by a water ballet for eight people. Since the 2000 Olympic Games, the Olympic programme has included the team event and the duet.
Alongside rhythmic gymnastics, synchronised swimming is the only exclusively female Olympic sport.
