Jon Stryker, 54
Estimated net worth: $1.2 billion
How we made his money: Family wealth, investments
Pet cause: The Arcus Foundation
The grandson of medical-supply pioneer Homer Hartmen Stryker, Jon Stryker has added to his substantial family fortune with a successful career as an architect and building rehabber. But he’s big on philanthropy, too, donating almost $250 million toward his two passions—gay rights and primate preservation. (The Myanmar snub-nosed monkey was named Rhinopithecus strykeri in his honor.) His biggest charitable effort is the Arcus Foundation, which recently endowed Kalamazoo College with more than $23 million for the creation of the Arcus Center for Social Justice Leadership.
Stryker’s personal life is a little complicated: Though he was married and has two children, he came out as gay after his divorce. Currently, he’s tri-coastal (sort of), with homes in Kalamazoo, Palm Beach and New York (in the ritzy Time Warner Building, no less). We haven’t dug up any reports of a significant other, so if you’re a power gay in one of those cities, feel free to look him up.
