A mention in the Daily Telegraph:

As it happens, it was the Rushdie affair that inspired the book in the first place. The essay writing contest was the idea of the Ammar Abdulhamid, a US-educated Syrian who became disillusioned with radical Islam after the fatwa issued against Rushdie by Iran. He pointed out to the American Islamic Congress that while the Muslim world had vast, well-organised networks of people pushing extremist visions, nobody was doing the same thing for liberal ideas. “What we need is an essay contest on liberty with significant cash prizes,” he said.
