Abigail Adams (née Smith; November 22, 1744 – October 28, 1818) was the wife and closest advisor of John Adams, as well as the mother of John Quincy Adams. She is sometimes considered to have been a Founder of the United States, and is now designated as the second first lady of the United States, although this title was not used at the time. She and Barbara Bush are the only two women to have been married to one U.S. president and the mother of another.
Adams's life is one of the most documented of the First Ladies: she is remembered for the many letters she wrote to her husband while he stayed in Philadelphia, Pennsylvania, during the Continental Congresses. John frequently sought the advice of Abigail on many matters, and their letters are filled with intellectual discussions on government and politics. Her letters also serve as eyewitness accounts of the American Revolutionary War home front.
