Ron Rosenbaum (born November 27, 1946) is an American journalist and author.

Rosenbaum was born into a Jewish family in New York City, New York and grew up in Bay Shore, New York. He graduated from Yale University in 1968 and won a Carnegie Fellowship to attend Yale's graduate program in English Literature, though he dropped out after taking one course. He wrote for The Village Voice for several years, leaving in 1975 after which he wrote for Esquire, Harper's, High Times, Vanity Fair, New York Times Magazine and Slate.

Rosenbaum spent more than ten years doing research on Adolf Hitler including travels to Vienna, Munich, London, Paris, and Jerusalem, interviewing leading historians, philosophers, biographers, theologians and psychologists. Some of those interviewed by Rosenbaum included Daniel Goldhagen, David Irving, Rudolph Binion, Claude Lanzmann, Hugh Trevor-Roper, Alan Bullock, Christopher Browning, George Steiner, and Yehuda Bauer. The result was his 1998 book, Explaining Hitler: The Search for the Origins of His Evil (Harper Collins. ISBN 0-679-43151-9).

David Vaughan Icke (pronounced /aɪk/, or IKE, born 29 April 1952) is an English writer and public speaker, best known for his views on what he calls "who and what is really controlling the world." Describing himself as the most controversial speaker in the world, he is the author of 19 books and has attracted a global following that cuts across the political spectrum. His 533-page The Biggest Secret (1999) has been called "the Rosetta Stone for conspiracy junkies."

Icke was a well-known BBC television sports presenter and spokesman for the Green Party, when in 1990 a psychic told him he was a healer who had been placed on Earth for a purpose, and that the spirit world was going to pass messages to him so he could educate others. In March 1991 he held a press conference to announce that he was a "Son of the Godhead" – a phrase he said later the media had misunderstood – and the following month told the BBC's Terry Wogan show that the world would soon be devastated by tidal waves and earthquakes. He said the show changed his life, turning him from a respected household name into someone who was laughed at whenever he appeared in public.
