The Smithsonian at 175

SI 175

2021 represents a significant chapter in the Smithsonian’s history—its 175th anniversary. On August 10, 1846, the U.S. Senate passed the act organizing the Smithsonian Institution, which was signed into law by President James K. Polk. As we commemorate this milestone, it is important to not only look back at where we have been, but also look ahead to what is on the horizon. Join us in person or online this coming year for a series of events that explore our history and imagine the Institution’s next 175 years.
