Learn how to be a member of the Culper Spy Ring with author Claudia Friddell at a colonial-era tavern. Visit interactive spy stations to learn how to write with invisible ink, use a clothesline to send secret messages like patriot Anna Smith Strong, and use a cipher to crack a code from Benjamin Tallmadge’s code book. Explore the history of Revolutionary spies including tools of the trade for a spymaster, the creation of America’s very first spy ring, and some of the men and women who put their lives in danger for their cause- Nathan Hale, Benjamin Tallmadge, and Lydia Darragh.  Free admission as part of Smithsonian Museum Day.
