Lyall H. Powers (born 1924) is a professor of English at the University of Michigan, where he has taught since 1958.[1] He was granted emeritus status by the University's Regents during their October, 1992, meeting.[2]
Powers has written widely on modern American authors, and, with Leon Edel, edited the complete notebooks of Henry James. One of his most widely circulated books is Alien Heart, a biography of Canadian author Margaret Laurence. A lifelong friend of Laurence, having met her when they were students together in the 1940s, Powers combines personal knowledge of the author with a study of her writings.
