Founded over 100 years ago and guided by the concept that a fraternity is an academic organization, we are the only professional chemistry fraternity in the nation. With over 70,000 members nationwide, we unite men and women pursuing a wide variety of chemistry-related careers.



Alpha Chi Sigma Fraternity was organized at the University of Wisconsin at Madison in late 1902 by a group of undergraduates in chemistry. The official date of founding is December 11, 1902. The first initiation took place in a cold cave on campus that was once an underground meteorological station. In September 1971, the first women were initiated into Alpha Chi Sigma.
