Alpha Chi Sigma (ΑΧΣ) is a professional fraternity specializing in the field of chemistry. It has both collegiate and professional chapters throughout the United States consisting of both men and women and numbering more than 69,000 members. The fraternity aims to bring together students and professionals pursuing a wide variety of chemistry-related careers.

History[edit | edit source]

Founding[edit | edit source]

The Alpha Chi Sigma fraternity was organized at the University of Wisconsin–Madison by a group of undergraduates who were fellow students in chemistry at that time. Later documents set the date of founding as December 11, 1902.

Famous Members[edit | edit source]
