The Megatherium Club

Many scientists lived in the Smithsonian Castle in its early years. These four young naturalists lived in the building and often collected for the Smithsonian on expeditions to new territories of the U.S. in the mid 1800s, and then lived in the Castle while they cataloged their specimen. Pictured clockwise from upper left are Robert Kennicott, Henry Ulke, Henry Bryant and William Stimpson. They dubbed themselves the "Megatherium Club" after an extinct giant sloth that had been recently discovered.
