Anthony Joshua was the eighth Olympic super-heavyweight boxing gold medallist, and this week he will become the sixth to try his luck in the professional ranks.
From champions to calamities, his predecessors have experienced almost every possible kind of boxing career.
Here Skysports.com casts its eye over their highs and lows.
1984 TYRELL BIGGS
A fringe contender through much of the late 1980s and early 1990s, Biggs was stopped in round seven of a world title challenge to Mike Tyson in 1987, and subsequently suffered knockout defeats to Riddick Bowe and Lennox Lewis.
1988 LENNOX LEWIS
Lewis, who won Olympic gold in a Canadian vest, switched to Britain and became an all-time great. Lewis was declared WBC champion in 1992 and crowned undisputed champion after a points win over Evander Holyfield in November 1999.
1992 ROBERTO BALADO
Brilliant Balado was one of the stars of the Cuban system. As well as his gold medal win in Barcelona he also won three World Amateur titles in 1989, 1991 and 1993. He died in a car accident in Havana in 1994.
1996 WLADIMIR KLITSCHKO
Unanimously accepted as the reigning heavyweight number one, Klitschko claimed his first title by beating Chris Byrd in October 2000 for the WBO belt. He has won 18 fights in succession since his last loss to Lamon Brewster in 2004.
2000 AUDLEY HARRISON
Harrison's spectacularly unsuccessful professional career appeared to have reached its juddering end in his one-round knockout by Deontay Wilder in Sheffield in April. But Harrison quickly reversed a retirement decision, and intends to fight on.
2004 ALEXANDER POVETKIN
The unbeaten Russian has held the WBA title in spurious circumstances since 2011, when Klitschko was upgraded to 'super-champion' status. Povetkin is due to meet Klitschko to decide the issue in Moscow in October.
2008 ROBERTO CAMMARELLE
The much-decorated Italian policeman has resisted the lure of the professional ranks despite claiming two world amateur titles and an Olympic medal of every colour. He was beaten by Joshua in the final of London 2012.
