Hedge fund manager and billionaire John Paulson donated $400 million to Harvard to support its engineering school, according to a university press release.

Harvard will rename the school after Paulson, who is a 1980 graduate of the Ivy League school. The university’s engineering school is already one of its fastest growing programs. Student enrollment in engineering classes is up 150% since 2007, and the school has beefed up the engineering faculty.

“John Paulson’s extraordinary gift will enable the growth and ensure the strength of engineering and applied sciences at Harvard for the benefit of generations to come,” says Drew Gilpin Faust, Harvard’s president.

Harvard has the largest endowment of any university in the country, valued at over $36 billion. Paulson’s donation only puts it further ahead of Yale University, the next biggest endowment with about $24 billion.
