So, let's be honest. There are only about 3 famous Swiss people. These 3 being -
1) Roger Federer
2) Martina Hingis
There are some people who, within Switzerland, are considered "famous" though.
The latest James Bond flick's director was Swiss. It was a big deal when he was chosen to direct (big deal aka, in Switzerland).
The Mr. & Ms. Switzerland winners are "famous."
... A friend of mine saw Martina Hingis yesterday.
I also saw Roger Federer a few years ago standing in front of a hotel, waiting for his car to be brought around.
