AXΣ Sigma Chapter
We are the Sigma Chapter of Alpha Chi Sigma at the University of California, Berkeley.
Alpha Chi Sigma is a professional co-ed fraternity whose brothers share a common interest in chemistry.
In practice, however, our brothers are involved in a wide variety of academic and professional pursuits!
Congratulations to our Spring 2022 Pledge Class!
The 3 Objects of the Fraternity:
its members with a tie of true and lasting friendship.
for the advancement of chemistry both as a science and as a profession.
its members by every honorable means in the attainment of their ambitions as chemists throughout their mortal lives.
At the University of Wisconsin at Madison on December 11th, 1902, nine undergraduate chemists convened to establish the Alpha Chi Sigma fraternity:
Raymond Tracy Conger
