William and Dorothy Stafford with Portland Poetry Festival Poster, 1993. (Courtesy of Lewis & Clark College Watzek Library Special Collections and Archives)This year marks the 100th year since the birth of Kansas poet William Stafford. Next time on KPR Presents, we'll find out how Washburn University is marking the occasion with a day of poetry readings and a keynote address by Stafford's son, author Kim Stafford. We'll also hear Pulitzer Prize-winning author Marilynne Robinson from her recent "Read Across Lawrence" event, and author Timothy Schaffert. Schaffert's latest book, The Swan Gondola, is a love story set at the 1898 World's Fair in Omaha...with a "Wizard of Oz" twist.
