  • Raymond Tracy Conger
  • Harold Everett Eggers
  • Joseph Gerard Holty
  • Alfred Emil Kundert
  • Joseph Howard Mathews

Day of the Week Sunday Monday Tuesday Wednesday Thursday Friday Saturday


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.


Membership to the Alpha Chi Sigma professional chemistry fraternity is open to collegiate and professional men and women with a strong interest in chemistry. Membership is for life. Those who are interested in becoming a member should contact their local (or nearest) collegiate chapter or professional chapter or group for further information about pledgeship and membership.
