1. Robert Young Hayne (1791–1839), a Charleston, South Carolina, lawyer, served in the state legislature and as state attorney general before his election to the U.S. Senate in 1822. He served there until 1832, making his mark as an anti-tariff proponent and as a strict constructionist and nullifier. He is best known for a series of speeches he made in the Senate in answer to Daniel Webster in 1830. Hayne was governor of South Carolina, 1832–34, during the nullification crisis; mayor of Charleston, 1835–37; and president of the Louisville, Cincinnati and Charleston Railroad from 1836 until his death (Sobel and Raimo, Biographical Directory of the Governors, 4:1400–1401).
