The majority of Douglas's fortune is derived from his family's 78% stake in publicly traded Investment AB Latour, according to the company's 2018 annual report.
Its investments include Assa Abloy, the world's largest lockmaker, according to its website. Douglas is credited with all of the assets because he founded the company.
The value of his cash investments is based on an analysis of dividends, insider transactions, market performance, taxes and charitable contributions.
Gustaf Douglas was born in 1938, the son of a Swedish count who was the country's ambassador to Brazil. He completed his MBA at Harvard Business School in 1964 and returned to Sweden.
He established Wasatornet, a family holding company, in 1980. Five years later, he bought control of investment company Hevea, whose stakes included security provider Securitas and engineering firm Trelleborg. Douglas recruited future billionaire Melker Schorling to be Securitas's CEO in 1987, the same year Hevea changed its name to Investment AB Latour.
Securitas sold shares on the Stockholm Stock Exchange in 1991. Latour remains its largest shareholder. The billionaire bought Boxholms Skogar, one of Sweden's largest forest owners, in 1998.
Douglas has been a board member of Sweden's Moderate Party since 2002, and was a prominent figure in their successful 2006 election campaign. He is married and has two sons.
