Oscar Leonard Carl Pistorius (/pɪsˈtɔːriəs/; Afrikaans: ; born 22 November 1986) is a South African former professional sprinter and convicted murderer. In 2015 he was found guilty for the 2013 murder of his girlfriend Reeva Steenkamp.
Both of Pistorius' feet had been amputated when he was 11 months old due to a congenital defect. When he was born he was missing the outside of both feet along with both fibula bones in his legs. Pistorius ran in both non-disabled sprint events and in sprint events for below-knee amputees. He was the tenth athlete to compete at both the Paralympic Games and Olympic Games.
After becoming a Paralympic champion, Pistorius attempted to enter non-disabled international competitions, over persistent objections by the International Association of Athletics Federations (IAAF) and charges that his artificial limbs gave an unfair advantage. Pistorius eventually prevailed in this legal dispute. At the 2011 World Championships in Athletics, Pistorius became the first amputee to win a non-disabled world track medal. At the 2012 Summer Olympics, Pistorius became the first double-leg amputee to participate in the Olympic Games.
