Matti Nykänen won Olympic gold in both individual ski-jumping events at the 1988 Winter Olympics.
Competing for Finland in Calgary, Nykänen won the normal hill individual event on February 14 and the large hill individual event on February 23. His victories made him the first ski jumper to win both individual hill titles at the same Winter Games.
Calgary 1988 also introduced the team ski-jumping event to the Olympic program, and Nykänen helped Finland win that gold as well. He therefore captured all three available ski-jumping gold medals, an exceptional achievement in Olympic history.
The other answer choices were notable competitors but did not win both individual events. Pavel Ploc took normal-hill silver, while Jens Weißflog and Ari-Pekka Nikkola finished outside the medals in the relevant individual results. Nykänen’s Calgary performance helped establish him as one of ski jumping’s greatest champions.
