Founded in 1886, Sigma Xi is a non-profit membership society of nearly 75,000 scientists and engineers who were elected to the Society because of their research achievements or potential. Some 180 Sigma Xi members are Nobel Laureates and many more have been elected to the National Academies of Science & Engineering. Sigma Xi has more than 500 chapters at universities and colleges, government laboratories, and industry research centers.
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 public understanding of science.
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.
