Cameron was born in Caledonia, New York, on July 4, 1826, the fifth child of seven born to Scottish Americanimmigrants Duncan and Sarah McColl Cameron. He attended Temple Hill Academy in Geneseo, New York, and then the Genesee Wesleyan Seminary in Lima, New York, which is now Syracuse University. He later studied law with the firm of Wadsworth and Cameron in Buffalo, New York. He graduated from the State and National Law School in 1853, was admitted to the bar, and practiced with Wadsworth and Cameron. He later formed a partnership with Frederick H. Wing, which was active in banking as Cameron & Wing.
In February 1875 the Wisconsin State Legislature, in joint session, elected Cameron to the United States Senate, and he served from March 4, 1875, to March 3, 1881. He did not seek reelection in 1881. During this term he was appointed chairman of a committee to investigate alleged election fraud in South Carolina during the disputed United States presidential election of 1876.
In February 1881 Senator Matthew H. Carpenter died in office, and on March 10 Cameron was elected to complete the remaining four years of his six-year term. Cameron took his seat on March 14, and served until March 3, 1885. He was not a candidate for reelection in 1885.
