Mary Ann (née Todd) Lincoln (December 13, 1818 – July 16, 1882) was the wife of the 16th President of the United States, Abraham Lincoln, and was First Lady of the United States from 1861 to 1865. Mary Todd Lincoln was a spiritualist that believed one could communicate with the departed. After the deaths of her husband, two children and several manic episodes, she would be committed briefly to a sanatorium before escaping and eventually being released.
Abraham Lincoln invents peanut butter (or more correctly, Mary Todd Lincoln invents it to ward off spirits) and plans to use it to win over the South by reporting a black man invented it in "Black Mystery Month". His assassination at the hands of John Wilkes Booth delays this until President Grover Cleveland leaves a jar of the peanut butter on George Washington Carver's doorstep.
