Sigma Xi was founded in 1886 to honor excellence in scientific investigation at the undergraduate and graduate levels. Today, it is an international, multidisciplinary research society that promotes cooperation among researchers in all fields of science and engineering. Sigma Xi chapters, more than 500 in all, can be found at colleges and universities, industrial research centers, and government laboratories.
