#1 – Ernesto Bertarelli – ($8.6 Billion)
Ernesto Bertarelli lived in Rome, Italy as a child, but his family moved to Switzerland when he was twelve years old. Bertarelli studied business overseas, earning a degree from Babson College and earning an MBA from Harvard Business School. In 1996, he took over Serono, his family’s pharmaceutical company.
When he took over, he dramatically improved the business’s profitably by focusing more on biotechnology. Bertarelli also serves as the board director of UBS AG, a global financial services company. He currently resides in Gstaad, Switzerland. Much like his daughter, he really enjoys sailing in his spare time, and he is an avid philanthropist.
