Who We Are

The Science History Institute is a multifaceted nonprofit organization. Our rapidly expanding collections and archives preserve scientific and technological artifacts of historic importance. The Institute’s museum and Othmer Library make these works readily available to the scientifically curious public and scientists alike. Distillations media—our magazine, blog, podcast, and videos—tell compelling stories at the heart of science and society. Meanwhile, our Institute for Research and Beckman Center for the History of Chemistry offer exceptional opportunities for academic scholarship. And our conference center is an elegant venue for creating unforgettable occasions. Headquartered in the heart of Philadelphia’s historic Old City neighborhood, the Institute is dedicated to making our scientific past present.
