Welcome to the homepage of Iowa State University’s Chapter of Sigma Xi.  Founded nationally in 1886, Sigma Xi is the international honor society for research scientists and engineers, with more than 500 chapters in North America and around the world. Membership is by nomination from a Sigma Xi member. Over the years, more than 200 Sigma Xi members have received the Nobel Prize. In addition to publishing American Scientist magazine, the non-profit Society awards hundreds of grants annually to student researchers and sponsors a variety of programs that support science and engineering. Sigma Xi has over 60,000 members and associate members, who are either affiliated with the more than 500 chapters and clubs or are active members-at-large.

Iowa State became the first pure Land Grant university to join as the 34th chapter in 1920.  Its first chapter president was R. E. Buchanan, then Dean of the Graduate Division.  The ISU Chapter has a mailing list of 389, of which 244 are active dues-paying members.  There are another 196 members in Ames and around the world.
