Abigail Adams was the wife and closest advisor of John Adams, as well as the mother of John Quincy Adams. She was a founder of the United States, and was the first second lady of the United States and second first lady of the United States, although such titles were not used at the time. She and Barbara Bush are the only two women to have been married to U.S. presidents and to have been the mothers of other U.S. presidents.
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 John Adams 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.
Surveys of historians conducted periodically by the Siena College Research Institute since 1982 have consistently found Adams to rank among the three most highly regarded first ladies by the assessments of historians.
