"Calhoun, the cast-iron man, who looks as if he had never been born, and never could be extinguished."
-Harriet Martineau
John C. Calhoun was, for his contemporaries, an unforgettable presence whether they despised or cherished him. Harriet Martineau, an English social theorist and pioneering feminist, made the above unforgettable observation. Compared to others of his opponents, she was positively kind. They saw him as the human embodiment of Milton's Satan, a burning bright Lucifer with magnetic personality and brilliant arguments for evil–in Calhoun's case for the "positive good" of racial chattel slavery. Yet even his supposed followers could recoil from him, or rather resent the strong hands by which he guided them.

Calhoun was born of a Scots family in the South Carolina backcountry. Raised a Democratic Republican, he was educated in the Federalist bastions of Yale College and the Lichfield Law School. Within a few short years following his graduation he had become one of the leaders of the House of Representatives, and from 1818 to 1824 he served as one of the most dynamic and effective peacetime American Secretaries of War. A contestant for President in the 1824 election, had he secured that office, the political history of the United States might have been somewhat altered. But as Vice President first to John Quincy Adams, and then to Andrew Jackson, he became enmeshed in South Carolina's struggles against the tariff and the power of the Federal government. For nearly the rest of his life, following his falling out with Jackson and his departure in 1832 from the office of the Vice President, Calhoun would serve as Senator from South Carolina, and leader of the Southern forces arrayed against the Northern forces that were bent on destroying the "Southern way of life"–by which they meant chattel slavery. While Calhoun's arguments might be thought to have died with the last guns of the Civil War, his political theories have had a long and curious afterlife.

All of this is made clear by Robert Elder in his new biography Calhoun: American Heretic. Bob is Assistant Professor of History at Baylor University. This is second book, and his second appearance on the podcast.
