The Bixby letter is a brief, consoling message sent by President Abraham Lincoln in November 1864 to Lydia Parker Bixby, a widow living in Boston, Massachusetts, who was thought to have lost five sons in the Union Army during the American Civil War. Along with the Gettysburg Address and his second inaugural address, the letter has been praised as one of Lincoln's finest written works and is often reproduced in memorials, media, and print.
Controversy surrounds the recipient, the fate of her sons, and the authorship of the letter. Bixby's character has been questioned (including rumored Confederate sympathies), at least two of her sons survived the war, and the letter was possibly written by Lincoln's assistant private secretary, John Hay.
