Alpha Chi Sigma () is a professional fraternity specializing in the fields of the chemical sciences.[1] It has both collegiate and professional chapters throughout the United States consisting of both men and women and numbering more than 70,000 members. The fraternity aims to bring together students and professionals pursuing a wide variety of chemistry-related careers.



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. 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

Coat of arms

The seven symbols that stretch the length of the coat of arms are the "seven metals of the Ancients": gold, silver, iron, mercury, tin, copper, and lead. These symbols correspond to planets, gods, and days of the week.[2]

Metal Gold Silver Iron Mercury Tin Copper Lead
God/celestial body Sol/Sun Luna/Moon Mars Mercury Jupiter Venus Saturn
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.

The Five Obligations of a Member:

  1. That a member will remember the Objects of the Fraternity and endeavor always to further them.
  2. That a member will pay promptly all financial obligations.
  3. That a member will so act so as never to be a reproach to Alpha Chi Sigma.
  4. That a member will cheerfully fulfill any assigned fraternal tasks.
  5. That a member will maintain as satisfactory a scholastic record as possible.


Membership to the Alpha Chi Sigma professional fraternity in the chemical sciences is open to collegiate and professional men and women with a strong interest in any of the chemical sciences related fields. 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.
