Episode 11. The 2006 ERB / Ray Bradbury discussion in Oak Park, Illinois continues with Chicago Muckers Jerry Spannraft and Joan Bledig. Jerry describes meeting Bradbury, who told him Edgar Rice Burroughs was the greatest American writer ever. In the context of Bradbury's “Fahrenheit 451,” Joan talks about changes to the wording in the paperback editions of the Tarzan books. “The author's words are his alone and should not be subject to change by anyone,” she says.
