Alleging that Edison was anti-Semitic are Stephen Esrati, a philatelic journalist in Shaker Heights, Ohio, and Ken Lawrence, a vice-president of the 56,000-member American Philatelic Society, who has researched Nazism and the postal service.

U.S. author Paul Auster, who wrote "The Invention of Solitude," said his father was hired "for a brief moment" as an assistant in Edison's library "only to have the job taken away from him the next day because Edison learned he was a Jew."

Car developer Henry Ford, known for anti-Semitic views, sent Edison a complete set of the notorious anti-Jewish work "The International Jew," author Allan Gould writes.
