Science History Institute

About this museum

Chemistry does not often get its own museum - which is precisely what makes the Science History Institute on Chestnut Street in Philadelphia so unusual and so rewarding. The Institute is dedicated to the history of the chemical and molecular sciences: the long, frequently surprising, sometimes heroic and sometimes troubling story of how humanity came to understand and manipulate matter at its most fundamental levels. The free museum on the ground floor presents that story through meticulously curated collections of scientific instruments, glassware, manuscripts, portraits, and artifacts that span the alchemical laboratories of the seventeenth century through the pharmaceutical and materials revolutions of the twentieth. The exhibits are designed to be accessible to non - scientists - you do not need a chemistry background to be captivated by an astrolabe, a Victorian chemistry set, or the story of how aspirin was developed - while offering enough depth to satisfy visitors with serious scientific backgrounds. The library and archival collections, while not publicly open without an appointment, represent one of the world's most significant repositories of material on the history of science and technology. With a 4.7 - star rating from more than 130 reviewers, the Science History Institute has built a loyal following among Philadelphia's intellectually curious visitors. Admission is free. Open Tuesday through Thursday from 10AM to 5PM, with extended Friday hours until 7PM - that late Friday closing makes it a particularly good option for visitors who want to explore after work or before a dinner reservation in Old City. The museum is located at 315 Chestnut Street. More information is available at sciencehistory.org. This is a genuinely distinctive institution that fills a gap in the cultural landscape with elegance and intelligence.
