Thomas Schmidheiny (born 1945) is a Swiss entrepreneur, former chairman of Holcim, the cement manufacturer. He is listed by Forbes magazine as the 527th richest person in the world as of 2016, when his net worth was estimated at US$4.1 billion.
Thomas Schmidheiny is the son of Max Schmidheiny (1908-1991). The family's construction materials empire (bricks, cement, etc) was divided in 1984, with Thomas inheriting Holcim, the concrete and cement company, and his brother Stephan, also a billionaire, was given the construction company Eternit.
Until 2003, Schmidheiny was the chairman of Holcim, one of the world's leading cement manufacturers, founded by his grand-uncle in 1912. Schmidheiny resigned his chairmanship as part of a deal to settle an investigation of insider trading in Spain. He has remained on the Board since that time. Since the merger between Holcim and Lafarge Thomas Schmidheiny detains 11.4% of the company Lafarge-Holcim and is the biggest shareholder of the firm.
