Dreyfoos’ largest gift has been $15,000,000 to MIT for the Stata Center, which consists of two buildings, named for Dreyfoos and Bill Gates. Dreyfoos dedicated this gift to his late mentor and MIT physics professor, Arthur C. Hardy. Dreyfoos has also endowed an Alexander W. Dreyfoos Professorship at MIT's Media Lab since 1995. Dreyfoos’ relationship with MIT has been continuous. In 2013 the MIT Corporation named the auditorium atop its Media Lab Complex in Dreyfoos’ honor for years of service. He remains a Life Member Emeritus of The MIT Corporation.
