In addition to publishing American Scientist,
Sigma Xi awards grants annually to promising young researchers, holds forums on critical
issues at the intersection of science and society, and sponsors a variety of programs
supporting honor in science and engineering, science education, science policy, and the

The Purdue University chapter of Sigma Xi was among the first in the nation. It was established
in 1909 as the 27th chapter out of the more than 500 chapters in existence today. Our chapter has
fostered and recognized outstanding research on the Purdue campus since 1909. We currently have
over 400 active members and sponsor activities at all
levels from high schools through post-graduate and faculty.
