of Engineering Science. He served as Secretary for the Midwest Mechanics Seminar, 1994-2003. Aref was president of the 20th International Congress of Theoretical and Applied Mechanics held in Chicago in 2000. In the 70+ years of these significant congresses they have been held three times in USA: In 1938 in Boston, MA, with MIT and Harvard University as the host institutions, in 1968 with Stanford University as the host, and in 2000 with a consortium led by University of Illinois, Urbana-Champaign as the hosts. Personal life and death Hassan Aref was born in Alexandria, Egypt. Previously a citizen of Canada, he acquired U.S. citizenship in 1998. He died from an aortic dissection.
