Harvard University says that alumnus John A. Paulson has made a $400 million endowment to support the School of Engineering and Applied Sciences (SEAS). The School will be renamed the Harvard John A. Paulson School of Engineering and Applied Sciences.

Since becoming a School, SEAS has added three undergraduate concentrations (biomedical engineering, mechanical engineering and electrical engineering) and a master’s program in computational science and engineering, the faculty has grown by nearly 30%, and course enrollment has increased by nearly 150%.

The School is also planning for expansion, where its scientists and engineers will occupy research and teaching facilities within a campus adjacent to Harvard Business School and the Harvard Innovation Lab.

Paulson graduated from Harvard Business School with high distinction in 1980. He founded Paulson & Co. in 1994 with $2 million and one employee. Today the company, which specializes in alternative investments, manages more than $19 billion and employs more than 125 people worldwide.
