A scholar and literary critic, Samuel Lynn Hynes Jr. attended the University of Minnesota before serving in the United States Marines as a torpedo bomber pilot during the Second World War. After completing his degree at the University of Minnesota, he earned his masters and doctorate degrees from Columbia University. Hynes taught at Swarthmore College from 1949 until 1968, Northwestern University from 1968 until 1976, and Princeton University from 1976 until his retirement as Woodrow Wilson professor of literature emeritus in 1990.
I am reading all of Graham Greene's works in chronological order during this pandemic (you have to do something!) and I'm throwing in to my reading order a few of the vast array of books written ABOUT Greene. Samuel Hynes has put together a helpful collection of essays written about Greene. I found the ones by W. H. Auden, Evelyn Waugh and Richard Hoggart most interesting. George Orwell's essay seriously attacks Greene, declaring frivolous Greene's "cult of the sanctified sinner." If you are a serious Greene fan, you'll enjoy this collection.
