Curling has two Olympic disciplines, the Teams and the Mixed Doubløes. Winning the World Championship in one discipline is not easy, let alone winning both. There are however four players that has done this.
Three ladies, all from Switzerland, Alina Pætz, Nadine Lehmann and Irene Schori.
The single male player to achieve this is Oskar Eriksson of Sweden that is also the only player to do it in a single season (2019).
