Alpha Chi Sigma is a National Co-Ed Professional Chemistry Fraternity.  It was founded December 11, 1902 at the University of Wisconsin-Madison. 

        The purposes of Alpha Chi Sigma are reflected in the three Objects of the Fraternity, which express the true ideals of all its members.

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.

        Alpha Chi Sigma brings together people from all fields related to Chemistry.  The members' backgrounds differ.  Members undergraduate majors range from Chemistry to BioChemistry to Chemical Engineering to Textile Chemistry to Biology as well as any other major where the candidate took a number of chemistry classes. 

        Collegiate members benefit from a local group to not only help with their studies, but also projects which teach the roles of leadership and management, invaluable in their careers. We also provide an opportunity to create lifelong friendships with others interested in chemistry. Sometimes it's just nice to walk into a room and be able to tell a chemistry joke.

        Our organization goes a step further. Actually many steps, as membership is for life. As a Professional member, further opportunities for meeting other members can help with your employment, hiring, and relaxation. Alpha Chi Sigma brings together a unique mix of people. Our Professional members appreciate meeting others involved in chemistry outside of their workplaces and often outside of their field of work.

        Purely professional organizations such as the American Chemical Society and the American Institute of Chemical Engineers have their place, and Alpha Chi Sigma constantly encourages its members to become active in these organizations. Social fraternities also offer much to the student, but only a professional fraternity—and Alpha Chi Sigma is the only national professional chemistry fraternity in the United States—can provide the college student and the professional in chemistry and related fields with the interests and bonds of a fraternity.
