Gregor Schlierenzauer (pronounced [ˈʃliːʁənt͡saʊ̯ɐ]; born 7 January 1990) is an Austrian ski jumper. He is one of the sport's most successful athletes of all time, having won the Ski Jumping World Cup, Four Hills Tournament, and Nordic Tournament twice each; the Ski Flying World Cup three times; as well as four medals at the Winter Olympics, five at the Ski Flying World Championships, and twelve at the Ski Jumping World Championships.
During his victorious 2008/09 World Cup season, Schlierenzauer set a number of ski jumping records, including surpassing Janne Ahonen's record of twelve individual World Cup wins with thirteen; and also tying Ahonen, Matti Hautamäki, and Thomas Morgenstern's record of six consecutive individual wins in a single season. On 26 January 2013, Schlierenzauer equalled Matti Nykänen's long-standing record of 46 individual World Cup wins, and currently has 53 to his name as of March 2017, which is a record shared with Sara Takanashi.
Gregor Schlierenzauer was born on 7 January 1990 in Innsbruck, Tyrol, to Paul and Angelika Schlierenzauer. The second of three children, he has an older sister, Gloria, and a younger brother, Lukas. His uncle is Markus Prock, the winner of three Winter Olympic medals in men's luge, who settled him a contract with Fischer Skis in 2001 and a few years later with Red Bull. Schlierenzauer is deaf in the left ear from birth. At age eight, Schlierenzauer began training in ski jumping at SV Innsbruck–Bergisel club. He attended an ordinary Austrian grammar school, however, due to tight schedules in both sport and school, he had problems keeping up with his class work. Schlierenzauer then enrolled at Skigymnasium Stams in Austria, the world's oldest ski-sport training center and boarding secondary school. He currently resides in Fulpmes, Tyrol.
