Curious about the other half of the Science History Institute? Step into the Othmer Library of Chemical History!

Since its founding in 1988, the Othmer Library at the Science History Institute has been a haven for research in the history of science—but there’s more to the story. Explore the reading room on a guided tour, learn how our collection has grown, and discover why we have one of the most comprehensive rare book collections on chemistry and its alchemical roots.


Othmer Library Tours are available every other Wednesday at 12pm. Starting in August, they will also be available on the first Friday of most months at 4pm.

Registration is required for Wednesday tours; First Friday tours will be drop-in. Guests under 14 years of age must be accompanied by an adult.
