Calvin Hoadley Upham (February 18, 1828 – February 26, 1892) was an American businessman, politician, and Wisconsin pioneer. He served one term in the Wisconsin State Assembly, representing Racine. He was a brother of William H. Upham, the 18th governor of Wisconsin. In historical documents, his name is almost always abbreviated as C. H. Upham.
Upham became associated with the Republican Party when it was established in the 1850s. He was elected city clerk in 1859, and was re-elected in 1860. In 1861, he held both offices of city clerk and city comptroller.[2] He was elected to the Wisconsin State Assembly in the Fall of 1861 and served in the 1862 session of the legislature. He represented Racine County's 1st Assembly district, which then comprised just the city of Racine.[3]
After the outbreak of the American Civil War, Upham became one of the founding donors and officers of the "Racine Soldier's Relief Society", which collected charity to outfit Racine's soldiers and care for their dependents.[2] He was later appointed an enrollment officer for the city of Racine, soliciting volunteers for service in the Union Army.[2] Towards the end of the war, he received a federal commission as a captain in the commissary and subsistence division and assigned to the Department of the Gulf. He served just over a year, from March 1864 through June 1865.[1][4]
In 1866, Upham moved north to Shawano, Wisconsin, to engage in the lumber business. While living there, he was an organizer and delegate to Wisconsin's 1868 "Soldiers' and Sailors' Convention", to select delegates to a national convention, to repudiate efforts to end Reconstruction and restore the political power of former Confederate sympathizers.[5] He was a partner in the corporation which was formed to purchase and overhaul the Milwaukee Sentinel in 1870, under Alexander McDonald Thomson.
Calvin Upham married Amanda E. Gibbs at Westminster, Massachusetts, in November 1851.[1] They had at least three children, though one died young.[9] Their son, Frederic William Upham, became a prominent businessman in Chicago.
