On 8 November 2012, Bradbury scholar Jon Eller presented the John D. Barlow Lecture at his home institution of Indiana University - Purdue University Indianapolis. In the lecture, Jon gives an account of Bradbury's development as an author, and shows how the later decades of Bradbury's career were drawn more towards Hollywood and the space programme, and less towards original fiction.
That said, he also points out the remarkable output of Bradbury's final decade, which saw the publication of two novels and many other books of short stories, poetry and essays.
Jon titled his lecture "Cry the Cosmos", after Bradbury's famous space-age essay for Life magazine. The lecture is now available in its entirety on YouTube, and the video includes images from Jon's presentation and a question and answer session.You can view the lecture here.
