Edwin McMasters Stanton – 1814-1869
Stanton succeeded President Abraham Lincoln’s first secretary of war, the notoriously corrupt Simon Cameron, on January 13, 1862. Once in charge, Stanton prosecuted the Civil War with ruthless energy. He was legendary for his ill temper and willingness to provoke disputes with other officials and with military commanders. The attempt of Andrew Johnson (who succeeded Lincoln after his assassination in April 1865) to remove Stanton from the Cabinet triggered Johnson’s impeachment.
