Anne Marshall is associate professor of history and executive director of the Ulysses S. Grant Presidential Library at Mississippi State University. Her book is "Cassius Marcellus Clay: The Life of an Antislavery Slaveholder and the Paradox of American Reform." Clay lived to be 92, had two wives and 11 children. Kentucky was his home state. As an antislavery reformer, Cassius Marcellus Clay is often remembered as a knife-wielding rabble rouser who both inspired and enraged his contemporaries. Abraham Lincoln made him minister to Russia. And yes, the boxer Muhammad Ali was originally named after him, but decided he wanted his own original name. Ann Marshall will discuss all this with us.
