About Stanford Sigma Xi

Main content start

Sigma Xi, The Scientific Research Honor Society, is the international honor society of science and engineering. One of the oldest and largest scientific organizations in the world (founded in 1886), Sigma Xi has a distinguished history of service to science and society for more than one hundred and twenty-five years. Scientists and engineers, whose research spans the disciplines of science and technology, comprise the membership of the Society. Sigma Xi chapters can be found at colleges and universities, government laboratories, and industry research centers around the world. More than 200 Nobel Prize winners have been members. Today, Sigma Xi has a total membership of nearly 60,000 scientists in over 500 chapters in the U.S., Canada and other countries, including Switzerland, Thailand, Lebanon, New Zealand and Australia. 

Stanford’s Sigma Xi chapter was established in the early 1900s, and it was a three-member commission of Stanford Sigma Xi members who oversaw reconstruction of the campus after the 1906 San Francisco earthquake. The chapter was continuously active for over a century until the 2010s, and was reactivated after a hiatus in 2022.
