4The Personal Memoirs of Ulysses S. Grant is an autobiography by Ulysses S. Grant, the 18th President of the United States, focused mainly on his military career during the Mexican-American War and the American Civil War, and completed as he was dying of throat cancer in 1885. The two-volume set was published by Mark Twain shortly after Grant's death.Twain created a unique marketing system designed to reach millions of veterans with a patriotic appeal just as Grant's death was being mourned. Ten thousand agents canvassed the North, following a script that Twain had devised; many were veterans who dressed in their old uniforms. They sold 350,000 two-volume sets at prices from $3.50 to $12, depending on the binding (roughly $100 to $330 in 2018). Each copy contained what looked like a handwritten note from Grant himself. In the end, Grant's widow, Julia, received about $450,000, suggesting a gross royalty before expenses of about 30%
