The Academy of Natural Sciences: First Natural Sciences Institution in the Americas

January 9, 2023

Founded in 1812 and located on the Benjamin Franklin Parkway in Philadelphia, the Academy of Natural Sciences of Drexel University has played an important role in fostering scientific research as the first natural sciences institution in the Americas. Since its inception, prestigious members have included Thomas Jefferson (whose fossil collection is housed at the Academy), John James Audubon, Charles Darwin and Marie Curie.

A leader in biological research, the Academy’s library and archives feature 200,000 books, including some that date back to the 1500s, that document an understanding of the natural world from the very beginning of modern science. Numerous scientific societies began at the Academy including the American Medical Association in 1847, American Association for the Advancement of Science in 1848, and in 1876, the American Entomological Society chose the Academy for its headquarters to house its collections and library. The Academy is involved in many environmental endeavors and offers programs to educate the public.

In over two centuries, the museum has amassed a collection of more than eighteen million specimens of noteworthy geographical, biological and historical significance, gathered from worldwide discovery expeditions, including hundreds of plants collected by Lewis and Clark.

Upon entering the building, the imposing Tyrannosaurus rex beckons in Dinosaur Hall, displaying over thirty towering frames of dinosaur species such as Avaceratops, Chasmosaurus, Corythosaurus, Deinonychus, Pachycephalosaurus, Tenontosaurus, and Tylosaurus.

In 1868, the Academy of Natural Sciences was the first museum in the world to mount a dinosaur skeleton. “Haddy,” or Hadrosaurus foulkii, was discovered in Haddonfield, New Jersey, just outside Philadelphia in 1858 and identified by Dr. Joseph Leidy. The public display generated enormous public interest.

Outside In is a children’s discovery center where young, inquisitive minds can explore the natural world while observing animal habitats. There are also dozens of historic dioramas portraying animals in their natural habitats throughout the museum.

To see paleontology in action, head to the Fossil Prep Lab where workers prepare fossils for study and display. Additional museum activities include live animal shows and naturalist presentations, allowing visitors to get up close and personal with creatures and specimens. Special events include Wild Wizarding Weekend, Bug Fest, Paleopalooza, Animal Superhero Weekend, Xtreme Science Days, and more.
