By most people’s standards, the Academy of Natural Sciences of Drexel University is old — founded in 1812, it’s the oldest natural sciences institution in the Western Hemisphere. But the Academy is a baby compared to the specimens it houses, some of which date back more than 350 million years.
Explorers Stephen Long and Ferdinand Hayden’s series of western wilderness expeditions formed the foundation of the Academy's 18-million-item collection, which it began displaying to the public in 1828. Over the subsequent 60 years, the Academy grew to three times its original size through donations, museum purchases, and daily doses of multivitamins. Now situated at 19th and Benjamin Franklin Parkway, the Academy houses more than 35 dioramas of plants and animals collected during global wildlife expeditions, a live animal center with ceiling-to-floor observation windows, and nearly a hundred mollusk specimens. A tropical garden hosts live butterflies from around the world, while Dinosaur Hall contains skeletal mounts of more than 30 Mesozoic species, including a 42-foot-long T. rex.
