Donald Campbell
Donald Malcolm Campbell, (23 March 19214 January 1967) was a British speed record breaker who broke eight absolute world speed records on water and on land in the 1950s and 1960s. He remains the only person to set both world land and water speed records in the same year (1964). He died during a water speed record attempt at Coniston Water in the Lake District, England.

Campbell formed part of perhaps Britain's most successful relay team – they won in the European Cup in 1999 and 2000, at the 2002 Commonwealth Games, and took the gold at the 2004 Athens Olympics (the first time a British team had done so since 1912). Campbell had also won a gold medal at the 2002 European Championships and a 2003 World Championship silver medal but had to return them when his running-mate, Dwain Chambers, tested positive for banned substances, sparking much animosity between the two. He won his last medal in 2006, again taking the relay gold at the European Championships, and he retired shortly afterwards. His personal bests of 10.04 s in the 100 m and 20.13 s in the 200 m—were not prodigiously quick by elite global standards, but over his career he earned an impressive reputation as a 'championship' runner, saving his best for finals and collecting significantly more medals than his times alone would indicate.
