#6 – Thomas Schmidheiny ($5.1 Billion)
Thomas Schmidheiny owns vineyards all around but the world, but he calls Klosters, Switzerland his home. In 1984, the Swiss man inherited his father’s cement manufacturing company, Holcim. Holcim had initially been founded in 1912, and to this day serves as one of the world’s top cement companies.
Schmidheiny served as chairman of Holcim for twenty years, successfully managing a company that his ancestors had cultivated for him. He ultimately stepped down as chairman in 2003, but he is still a member of Holcim’s Board. Today, he still owns approximately 12% of the highly successful international company.
