The country’s richest real estate tycoon is hoping to woo Amazon to build its second headquarters in Irvine, California, despite long odds. Through his company Irvine Co., Bren already sits on 120 million square feet of real estate, mostly in coastal California. He studied business administration and economics at the University of Washington on a skiing scholarship. An ankle injury, however, sidelined him from trying out for the 1956 Olympics. The California native has donated more than $220 million to California schools and universities.
