Salmon P. Chase, Mathew B. Brady & Co., c. 1862

Secretary of the Treasury

To manage the nation’s finances, Lincoln called upon Senator Salmon P. Chase of Ohio, a leading spokesman for black freedom and equality and another rival for the Republican nomination. The highly capable but keenly ambitious Chase served well but he often wrangled with other cabinet members, particularly Seward. Chase oversaw the establishment of a national banking system and modern banknotes to fund the war before Lincoln appointed him chief justice of the Supreme Court in 1864.
