Elihu Benjamin Washburne (September 23, 1816, Livermore, Maine – October 23, 1887, Chicago, Illinois) was one of seven brothers who played a prominent role in the early formation of the United States Republican Party. He later served as United States Secretary of State in 1869.
In March 1839, Washburne had saved enough money and entered Harvard Law School. A year later, in 1840 he graduated and passed the Bar. Afterwards, Washburne left Massachusetts and settled West in Galena, Illinois, hoping to make his fortune.
Washburne, a resident of Galena, Illinois, represented northwestern Illinois in the United States House of Representatives from 1853 to 1869. While in Congress, he was also a member of the powerful Appropriations Committee.
He was known for his courage, and met President-elect Abraham Lincoln upon his arrival in Washington, D.C. on February 23, 1861. An assassination attempt was feared, and other Republican Party leaders were afraid to take on this duty. Washburne and his brothers had hidden the whereabouts of President-elect Lincoln by personally cutting telegraph wires in key locations.
