The title character in Vivian Neuwirth’s Mr. Toole is John Kennedy Toole, author of the 1981 Pulitzer Prize novel A Confederacy of Dunces. Known as “Ken” to family and friends, Toole died in 1969, more than a decade before his book was published. Neuwirth knew Toole when she was a student at St. Mary’s Dominican High School in New Orleans, where he taught English. “He was,” she says, “an amazing teacher” with a “theatrical flair.”
