The Academy of Natural Sciences of Drexel University is America's oldest natural science research institution and museum, founded in 1812 and sitting right on the Benjamin Franklin Parkway in Logan Square. Walk in and you'll find over 18 million specimens housed within its walls. The real draw, though? Dinosaur Hall. That's where visitors come face to face with a complete Tyrannosaurus rex skeleton and other prehistoric creatures that've captivated audiences for generations.[1]
Back in 2011, the Academy joined forces with Drexel University, becoming the Academy of Natural Sciences of Drexel University while keeping its historic mission alive. Research, education, public engagement. Those remain the core. The museum still runs serious scientific work in ornithology, malacology, ichthyology, and environmental science, all while serving up one of Philadelphia's best family museum experiences.[2]
History
Founding
On March 21, 1812, a handful of Philadelphia naturalists gathered with a mission: establish an institution "for the encouragement and cultivation of the sciences, and the advancement of useful learning." The founding members weren't household names, but they mattered. Apothecary John Speakman, dentist Jacob Gilliams, and several others who cared deeply about natural history got the ball rolling.
Here's what made this place unique: it was the first institution of its kind in the entire Western Hemisphere, beating out similar organizations that would come later around the world.
Early Years
In its early decades, the Academy moved fast:
- Built collections through expeditions and donations
- Published the Journal of the Academy of Natural Sciences (first American natural history journal)
- Hosted lectures by leading scientists
- Developed important research programs
Notable Scientists
Some serious naturalists have been part of this place:
- Thomas Say — "Father of American Entomology"
- John James Audubon — Donated bird specimens
- Joseph Leidy — Pioneer paleontologist
- Edward Drinker Cope — Dinosaur hunter and "Bone Wars" participant
Current Building
The Academy moved to its present location on the Benjamin Franklin Parkway in 1876. That wasn't the end of it, though. Major renovations and expansions happened over the decades. Today the building sits across 19th Street from the Franklin Institute, facing it directly.
Drexel Affiliation
Financial stability was crucial. In 2011, the Academy partnered with Drexel University, which solved that problem without sacrificing what made it special. Its independent research mission and public museum stayed intact.
Exhibits
Dinosaur Hall
This is the main event. What you'll see:
- T. rex: Complete Tyrannosaurus rex skeleton
- Giganotosaurus: One of the largest meat-eating dinosaurs ever discovered
- Hadrosaurus foulkii: Cast of the first dinosaur found in America (New Jersey, 1858)
- Interactive displays that explain how we understand dinosaurs
- Fossil preparation lab where you can watch the work happen
Butterflies!
This one's different. You're not looking at specimens behind glass:
- Hundreds of tropical butterflies flying around freely
- Walk-through tropical habitat
- Seasonal operation (check the website for when it's running)
- Educational programs covering butterfly life cycles
Outside In
Kids need to touch things. This space lets them:
- Observe and touch live animals
- Visit nature discovery stations
- Climb a tree house structure
- Dig for fossils in a dedicated pit

Research
Scientific Collections
The numbers tell the story. Over 18 million specimens total:
- Birds: 200,000+ specimens (one of the world's largest collections)
- Fish: 1.2+ million specimens
- Mollusks: 10+ million specimens
- Plants: 1.4+ million specimens
- Insects: Millions of specimens
Research Departments
The work continues across multiple areas:
- Ornithology
- Ichthyology
- Malacology
- Entomology
- Botany
- Environmental Science
Publications
They don't just collect. The Academy publishes scientific journals and research papers that advance our understanding of natural history and environmental science worldwide.
