Richard Warrington Baldwin Lewis (November 1, 1917 in Chicago, Illinois - June 13, 2002 in Bethany, Connecticut) was an American literary scholar and critic. He gained a wider reputation when he won a 1976 Pulitzer Prize for Biography or Autobiography, the first National Book Critics Circle Award for nonfiction, and a Bancroft Prize for his biography of Edith Wharton. The New York Times called the book "a beautifully wrought, rounded portrait of the whole woman, including the part of her that remained in shade during her life" and said that the "expansive, elegant biography ... can stand as literature, if nothing else." He was the Neil Gray Professor of English and American Studies at Yale University, where he taught from 1959 until his retirement in 1988; from 1966 to 1972, he was master of Yale's Calhoun College. From 1954 to 1959 he taught at Rutgers–Newark. In 1988 Lewis received a Litt.D. from Bates College. A member of the American Academy of Arts & Sciences, Lewis received its Gold Medal for Biography in 2000. Lewis is generally considered one of the founders of the academic field of American Studies, and was regarded as one of the finest Americanists of his generation. His interests ranged from criticism of American and European writers to biography and artistic criticism. Lewis' career as critic involved him in the lives of many influential American and European thinkers and writers. Lewis received his doctoral degree from the University of Chicago, where he studied under Norman Maclean, author of the novel A River Runs Through It and Other Stories. He and his wife and sometime co-author Nancy later became close friends with Southern writer Robert Penn Warren.
