Z.Y. Fu
Zai Yuan Fu (傅在源) is a mysterious Chinese businessman who lent his name (and money) to SEAS. He is not an alum, however, and gave his generous gift of $26 million at age 78. He was the founder of Sansiao Trading Company, which apparently deals in grains and bean trading. Someone has to sell those things, anyway.
Everyone still calls the school SEAS, though.
