Mary Todd Lincoln, 16th First Lady of the United States (d. 1882)
Mary Ann Todd Lincoln (December 13, 1818 – July 16, 1882) was First Lady of the United States from 1861 to 1865 as the wife of President Abraham Lincoln.

Mary Lincoln was a member of a large and wealthy, slave-owning Kentucky family. She was well educated. Born Mary Ann Todd, she dropped the name Ann after her younger sister, Ann Todd (later Clark), was born. After finishing school during her teens, she moved to Springfield, Illinois, where she lived with her married sister Elizabeth Edwards. Before she married Abraham Lincoln, she was courted by his long-time political opponent Stephen A. Douglas. The Lincolns had four sons of whom only the eldest, Robert, survived both parents. Their family home and neighborhood in Springfield is preserved at the Lincoln Home National Historic Site.

Lincoln staunchly supported her husband throughout his presidency and was active in keeping national morale high during the Civil War. She acted as the White House social coordinator, throwing lavish balls and redecorating the White House at great expense; her spending was the source of much consternation. She was seated next to Abraham when he was assassinated in the President's Box at Ford's Theatre on Tenth Street in Washington, D.C. on April 14, 1865. The deaths of her husband and three of her sons weighed heavily on her.

Lincoln suffered from numerous physical and mental health issues during her life. She had frequent migraines, which were exacerbated by a head injury in 1863. She was depressed for much of her life; some historians think she may have had bipolar disorder. She was briefly institutionalized for psychiatric disease in 1875, but later retired to the home of her sister. She died of a stroke in 1882 at age 63.
