Thomas Hauser has authored 50 books on subjects ranging from professional boxing to Beethoven. His most celebrated work is Muhammad Ali: His Life And Times - the definitive biography of the man who was once the most famous person on earth. The British edition was honoured with the William Hill Book of the Year Award. Hauser's first book – Missing – was nominated for the Pulitzer Prize, Bancroft Prize, and National Book Award, and served as the basis for the Academy-Award-winning film starring Jack Lemmon and Sissy Spacek. Subsequently, he co-authored Final Warning: The Legacy of Chernobyl, which secured his reputation as a responsible and reliable social critic. The film version of Final Warning starred Jon Voight and Jason Robards. Each year, the University of Arkansas Press publishes the articles that Hauser has written about boxing during the preceding 12 months in book form. In 2004, he was honoured by the Boxing Writers Association of America with the Nat Fleischer Award for Career Excellence in Boxing Journalism.
