Publisher Houghton Mifflin Harcourt said in a statement Monday, May 20, 2013, that Waber died May 16 at his Long Island home after a long illness. He was 91. Waber debuted as an author in 1962 with "The House on East 88th Street." The book introduced readers to the loveable Lyle, first spotted in a bathtub in an Upper East Side brownstone. Lyle's story continued in "Lyle Finds His Mother," "Lyle and the Birthday Party." (AP Photo/Houghton Mifflin Harcourt)
