122. Ted Lerner & family
Lerner and his family added to their 20 million square feet of commercial and retail space in 2016, when they opened 1775 Tysons Boulevard, a 17-story office tower. The tower is a cornerstone of their Tysons, Virginia, master-planned development. Since 2006, Lerner has owned the Washington Nationals baseball team, which made the National League playoffs in September.
