Pulitzer Prize-winning poet and memoirist Tracy K. Smith, winner of the 16th annual Robert Creeley Award, will take the stage at a public reading March 29 at 7:30 p.m. in the Acton-Boxborough Regional High School auditorium. The event is free and open to the public. Each year, the Robert Creeley Foundation honors the legacy of Creeley — an Acton native, award-winning poet, and teacher — through its award to an internationally renowned poet. Each year’s award winner travels to Acton to give a public reading, visit local schools, and select and sign books to add to the Acton Memorial Library’s collection. Smith’s 2011 collection, “Life on Mars,’’ won the 2012 Pulitzer Prize for Poetry. Raised in Falmouth, she is now the director of Princeton University’s creative writing program.Jennifer Fenn Lefferts can be reached at firstname.lastname@example.org.
