General George Washington's original sleeping and office marquee, or tent, from the Revolutionary War was carefully preserved by generations of the Custis and Lee families following the deaths of George and Martha Washington. In 1909, Reverend W. Herbert Burk of Norristown, Pennsylvania, purchased the tent from Mary Custis Lee, daughter of Confederate General Robert E. Lee. Reverend Burk considered the tent the “supreme relic of Washington,” and he made it the centerpiece of an American history museum he established at Valley Forge. Today, the tent is on view at the Museum of the American Revolution in Philadelphia.
