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.

Thomas Paine and Joseph Priestley are seated at a table with guns, knives, a dish says phospherous, a gun butt says "Royal Electric fluid." A winged puti grins at them squatting in the center of the table. Books on treason, murders, assistination, revolution, etc. surround them. At Priestley's feat are packages of brimstone, axe and pickax. On the walls are scenes of execution and assassinations.
