John H McWhorter is an associate professor of English and comparative literature at Columbia University. He earned his B.A. from Rutgers, his M.A. from New York University, and his Ph.D. in linguistics from Stanford. His linguistic and literature backgrounds come in handy when he lectures F&C students on Jean-Jacques Rousseau and explains why it was so unfortunate for Mr. Rousseau that his last name sounded a lot like "ruisseau," the French word for "stream."
Professor McWhorter is an author of more than a dozen books including The Power of Babel: A Natural History of Language, Losing the Race: Self Sabotage in Black America and Our Magnificent Bastard Tongue: The Untold History of English. In 2016 he published Words on the Move: Why English Won't - and Can't - Sit Still (Like, Literally). He also regularly contributes to newspapers and magazines including The New Republic and The Atlantic. Students might be particularly interested in his article on how immigrants change languages in The Atlantic and an essay on policing the "N-word" in Time.
