Born in Stark, New York, Pierce was the son of Duane and Mary (Morse) Pierce. He attended public and private schools, and taught school before deciding to become a doctor. In 1862, he graduated from Eclectic Medical College in Cincinnati, Ohio. He practiced medicine in Titusville, Pennsylvania from 1862 to 1866, and moved to Buffalo, New York in 1867.
Pierce engaged in the manufacture and sale of patent medicines and established the Invalids' Hotel and Surgical Institute. His manufacturing business started with "Doctor Pierce's Favorite Prescription", which he followed with other medicines, including Smart Weed and Dr. Pierce's Pleasant Pellets. His venture proved a success, with nearly one million bottles of Dr. Pierce's Smart Weed and other preparations shipped annually.
He was a member of the New York State Senate (31st D.) in 1878 and 1879. Pierce was elected as a Republican to the 46th United States Congress, holding office from March 4, 1879 to September 18, 1880, when he resigned.
After leaving Congress, Pierce resumed his business interests, and was publisher of a book, the People's Common-sense Medical Adviser.
Pierce was married to Mary Jane Smith. They were the parents of five children, three of whom reached adulthood; V. Mott, Hugh C., and Waldo.
