Olympians in Switzerland

Passing through a small neighbouring village in Switzerland, with about 1,000 inhabitants, I saw this sign which congratulates 3 of the residents for participatinging in the games. WOW, I thought, 3 out of a 1,000, there must be something special in the air here! Also what a nice gesture to congratulate them at the entrance to the place.
It was only when I investigated further that I found one of them was Jo-Wilfried Tsonga, who was playing tennis for France! Obviously he is a tax exile from M. Hollande.
In nearby Switzerland we also have Jackie Stewart and Michael Schumacher.
