<P> Tennis was an Olympic sport from the inaugural 1896 Summer Olympics through the 1924 Games, then was dropped for the next 64 years (except as a demonstration sport in 1968 and 1984) before returning in 1988 . As there were only three Major championships designated by the International Lawn Tennis Federation before 1925, none of the tennis players who participated in the Olympics between 1896 and 1924 had a chance to complete a Golden Grand Slam . However, there was a possibility to complete a Career Golden Grand Slam by winning the 1920 Olympics or 1924 Olympics plus each of the four grand slams, all of which were present from 1925 onwards . The term Golden Slam (initially "Golden Grand Slam") was coined in 1988 . </P> <P> Only one player has completed the Golden Slam: </P> <Dl> <Dd> Steffi Graf (1988 Australian Open, 1988 French Open, 1988 Wimbledon Championships, 1988 US Open, and 1988 Olympic gold medal) </Dd> </Dl> <Dd> Steffi Graf (1988 Australian Open, 1988 French Open, 1988 Wimbledon Championships, 1988 US Open, and 1988 Olympic gold medal) </Dd>
