Before he became a best-selling and Pulitzer Prize-winning author, Frank McCourt was a teacher in New York City's public school system. McCourt's new book, "Teacher Man" chronicles his 30-year teaching career, and he'll read from it tonight at the Northshire Bookstore. He recently spoke with Mitch Wertlieb about his years as a teacher and the new book. © Copyright 2012, VPR
