#5 – Hansjörg Wyss ($5.9 Billion)
Hansjörg Wyss doesn’t really live in Switzerland anymore, but it’s where the entrepreneur got his start to begin with. He was born in Bern in 1936 and he graduated from the Swiss Federal Institute of Technology Zurich with a Master of Science degree. He would later go on to study at Harvard University and earn an MBA.
Wyss took on a variety of different jobs in the textile and steel industries once he completed his studies, and he ended up meeting one of the co-founders of Synthes, a Swiss medical device manufacturer. By 1997, Wyss had founded Syntheses USA. The company has been highly successful, and he only stepped down as company chairman when Johnson & Johnson acquired the company for $21.3 billion in 2012.
