General Washburn was born in Windsor, Vt., March 28, 1832. His parents moved to Ohio during his infancy. He received a common school education and at fourteen began teaching school. He entered Oberlin College, but did not complete his course. At eighteen he went to Indiana where he resumed school-teaching. At twenty-one he entered the New York State and National Law School, from which he graduated. At twenty-three he was elected auditor of Vermilion county, Indiana.

His war record was a highly honorable one. He entered the army as private in 1861 and left it as brevet brigadier-general in 1865. His service was mainly identified with the Eighteenth Indiana, of which he became colonel. He was in several of the western campaigns, notably in that of Vicksburg, in which he bore a prominent part. In the last year of the war he was with Sherman’s army, and for a short time after its close was in command of a military district in southern Georgia. In 1864, he was elected to Congress over the Hon. Daniel W. Voorhees, and again, in 1866, over the Hon. Solomon W. Claypool. At the expiration of his second term he was appointed by President Grant, surveyor-general of Montana, which office he held until his death.
