Peter John Gomes (May 22, 1942 – February 28, 2011) was an American preacher and theologian, the Plummer Professor of Christian Morals at Harvard Divinity School and Pusey Minister at Harvard's Memorial Church — in the words of Harvard's president "one of the great preachers of our generation, and a living symbol of courage and conviction."

Gomes was born in Plymouth, Massachusetts, the son of Orissa (White) and Peter Lobo Gomes. His father was from the Cape Verde Islands and his mother was African-American. DNA testing revealed that he was likely descended from the Fulani, Tikar, and Hausa peoples of West Africa, and that his patrilineal line likely leads to some Sephardic Jewish ancestry. He was baptized as a Roman Catholic, but later became an American Baptist.

After earning his AB from Bates College in 1965 and STB from Harvard Divinity School in 1968, Gomes was ordained by the First Baptist Church of Plymouth, Massachusetts, (where he occasionally preached throughout his life). After a short tenure at Tuskeegee,^{[clarification needed]} he returned^[when?] to Harvard, where in 1970 he became Pusey Minister in Harvard's nondenominational Memorial Church, and in 1974 was made Plummer Professor of Christian Morals.

Christopher Eric Hitchens (13 April 1949 – 15 December 2011) was an English American author and journalist whose career spanned more than four decades. Hitchens, often referred to colloquially as "Hitch", was a columnist and literary critic for New Statesman, The Atlantic, The Nation, The Daily Mirror, The Times Literary Supplement and Vanity Fair. He was an author of twelve books and five collections of essays. As a staple of talk shows and lecture circuits, he was a prominent public intellectual, and his confrontational style of debate made him both a lauded and controversial figure.

Hitchens was known for his admiration of George Orwell, Thomas Paine and Thomas Jefferson, as well as for his excoriating critiques of various public figures including Mother Teresa, Bill Clinton, Henry Kissinger and Diana, Princess of Wales. Although he supported the Falklands War, his key split from the established political left began in 1989 after what he called the "tepid reaction" of the Western left to the Rushdie Affair. The September 11 attacks strengthened his internationalist embrace of an interventionist foreign policy, and his vociferous criticism of what he called "fascism with an Islamic face." His numerous editorials in support of the Iraq War caused some to label him a neoconservative, although Hitchens insisted he was not "a conservative of any kind", and his friend Ian McEwan describes him as representing the anti-totalitarian left.
