This is a carte de visite of General William Tecumseh Sherman who was a partner with his brother-in-law, Thomas Ewing, Jr, in the law firm Sherman, Ewing and McCook in Leavenworth, Kansas Territory. Sherman came to Leavenworth in September 1858 and he left 14 months later in 1859 to take a position at a military school in Louisiana. The military school was forerunner of what is now Louisiana State University at Baton Rouge. Later, Sherman gained fame as a Union general in the Civil War (1861-1865).
