History

The Alpha Chi Sigma fraternity was organized at the University of Wisconsin at Madison in late 1902, 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. The original founders were:

• Raymond Tracy Conger
• Harold Everett Eggers
• Joseph Gerard Holty
• Alfred Emil Kundert
• Joseph Howard Mathews
• Edward Gustav Mattke
• Bart Eldred McCormick
• Frank Joseph Petura
• James Chisholm Silverthorn

Purpose

The Three Objects of Alpha Chi Sigma:

1. To bind its members with a tie of true and lasting friendship.
2. To strive for the advancement of chemistry both as a science and as a profession.
3. To aid its members by every honorable means in the attainment of their ambitions as chemists throughout their mortal lives.
