After James Madison left the Presidency, they returned home to Virginia, where she helped her husband organize his papers including the notes he used in drafting the Constitution.
After her hubby died and she returned to D.C. she was awarded an honorary seat in Congress. Making her the first woman with a seat (while powerless) in the the Congress. She was the first private citizen to transmit a message via telegraph (an honor given to her by Sam Morse of morse code fame).
Dolly Madison was known for exercising actual political influence (a first for First Ladies), became our first female public celebrity and loaded up loot from the white house, delaying departure for hours with the British on their way to burn it down.
She was a heavy featured woman who stood 2.5 inches above her husband and had a great mind and heart. Dolly Madison kicked ass!
