Born in Hebron, New York, Hopkins attended the common schools as a child and later became a telegraph operator. He moved to Madison, Wisconsin in 1849 and served as a private secretary to Governor Coles Bashford in 1856 and 1857. He was a member of the Wisconsin Senate in 1862 and 1863 and served in the Wisconsin State Assembly in 1866. Hopkins was elected a Republican to the United States House of Representatives in 1866 as part of the 40th United States Congress to represent Wisconsin's 2nd congressional district. He was reelected to the 41st Congress and served from 1867 until his death in Madison, Wisconsin on January 1, 1870. His death created a vacancy in congress that was filled by David Atwood for the remainder of the 41st Congress.
