Billy Collins is one of today?s most popular poets, revered for his ability to evoke humor and heartbreak in verses both subtle and sagacious. Collins served as U.S. poet laureate from 2001 to 2003 and has taught English at Lehman College of the City University of New York for more than 30 years. He?ll speak on Monday night at Union South as part of the Distinguished Lecture Series, which is also part of the UW-Madison student-organized Madison Lit Fest.
