ELKINS PARK, Pa. (AP) — The founder of the Dead Poets Society of America suffered a fatal heart attack little more than a month after commissioning his own tombstone. Walter Skold enlisted the son of novelist John Updike to carve a unique tombstone that will be topped with a dancing skeleton and a quill. Michael Updike, who received the poet's deposit last month, said he never expected to be carving the monument so soon.
