The tour takes approximately one hour and includes the Bishop White House. Built in 1775, it was occupied from 1791 -1793 by lawyer John Todd, and his wife Dolley Payne. Todd died during the 1793 yellow fever epidemic. Following her husband's death, Dolley married James Madison, destined to become the fourth President of the United States. The couple subsequently moved to the Madison estate in Virginia. The Todd House reflects the lifestyle of 18th century Philadelphia's middle class.
