The Science History Institute: Illuminating the Hidden Stories of Science in Philadelphia

The Science History Institute stands as one of Philadelphia’s most distinctive museums and research centers, dedicated to exploring how discoveries in chemistry, engineering, and the life sciences shape our world. From rare books and archival treasures to interactive galleries and public programs, the Institute bridges the gap between scientific innovation and cultural history, making it an essential destination for anyone curious about the forces that drive human progress.

Origins and Mission: Connecting Curiosity with Heritage

Founded in 1982, originally as the Center for History of Chemistry, the Institute sprouted from an idea to preserve the legacies of chemists whose work had fundamentally transformed society. Today, housed in a stately 1865 bank building at 315 Chestnut Street, it welcomes visitors into the heart of Old City, steps from Independence Hall and the Liberty Bell, offering a vibrant mix of permanent and temporary exhibits, educational outreach, and scholarly resources.

The Institute’s mission: to collect, preserve, and interpret artifacts and stories from the history of science—especially chemistry, chemical engineering, and allied fields—to foster public understanding and appreciation for how scientific developments are embedded in our daily lives.

Collections That Span Centuries of Discovery

At the core of the Science History Institute’s impact are its world-class collections, open to all:

• Othmer Library of Chemical History
  Holding more than 150,000 books and journals in 15 languages plus over 7,000 rare volumes from the 15th–19th centuries, the Othmer Library is the world’s leading repository for the study of chemistry and alchemy. Among its holdings: Newton’s handwritten manuscripts, classic dye sample books, lab reports, and treatises charting the evolution of modern chemistry.
• Archives, Photographs, Oral Histories, and Videos
  Researchers have access to more than a mile and a half of archival materials, including documents, photos, and films from scientists, companies like Dow and Rohm & Haas, and organizations such as the International Union of Pure and Applied Chemistry. The Institute’s oral history center preserves over 1,200 interviews dating back to 1979, revealing unique human stories from Nobel laureates to immigrant inventors.
• Museum Collections: Art, Instruments, and Objects
  Over 6,500 artifacts and more than 500 works of art highlight science’s place in everyday life. From a Bakelite bracelet and mass spectrometer to oil paintings of alchemists and watercolors of technical processes, every object is a portal to the roots and reach of scientific advancement.
• Digital Collections and Research
  The digital archive makes over 14,000 items accessible worldwide, from rare books to advertisements, oral histories, letters, and scientific instruments.

Exhibitions: Interactive and Immersive Learning

Visitors to the Institute step into a world where 500 years of chemistry and its global impact come alive. Permanent exhibitions showcase everything from early glassware and Boyle’s oil portrait to iconic inventions and colorful consumer goods. Interactive “object explorer” tables let guests unlock the stories of household items like oven mitts and flip-flops, revealing the scientific processes that changed everyday life.

Rotating exhibitions, such as 2022’s “Downstream,” trace environmental challenges like water analysis in the Delaware Valley, while other displays celebrate plastics, pharmaceuticals, and the human dimension of innovation. The galleries are free and open Wednesday through Saturday—ideal for students, families, and science fans alike.

Education, Research, and Community Engagement

The Institute is more than a museum; it’s a vibrant educational center. Programs include school tours, scavenger hunts, lectures, creative workshops, and the Collections Blog, which features stories behind the artifacts and manuscripts. Scholars from around the world can schedule research appointments in the Jacobs Reading Room to study primary sources, rare books, and historic documents.

Through exhibitions and digital outreach, the Institute highlights the intersection of science with social issues like race, immigration, and gender, offering materials such as the papers of Percy Lavon Julian—a Black research chemist known for synthesizing medicinal drugs from plants—and Jewish chemists’ correspondence from Nazi-occupied Germany, newly digitized through grants and partnerships.
