Soros announced his engagement to family and friends gathered at his house in Southampton on Long Island Saturday to celebrate his birthday, according to a person who attended and asked not to be named because the party was private.
The couple met in 2008 at a luncheon in New York, the person said. Soros proposed to Bolton, 40, on a recent weekend. Michael Vachon, a spokesman for Soros, declined to comment.
Bolton is a health-care and and education consultant who most recently developed a Web-based yoga-education platform, the person said. She graduated from the University of Utah and has an MBA from the University of Miami. It will be her second marriage and Soros's third.
Soros is chairman of New York-based Soros Fund Management LLC, his former hedge fund that became a family office last year. The office oversees $25 billion for Soros, his family and foundations.
The Hungarian emigre, who ranks 21st on the Bloomberg Billionaires Index, stepped back from day-to-day money management in 1989 to spend more time on philanthropic work. In the past three decades, he's given away more than $8 billion to promote democracy, foster free speech, improve education and fight poverty around the world, according to his Bloomberg Billionaires biography. He has five children from his previous marriages.
The couple told their friends the wedding will take place next summer, the person said.
