John Joseph Loftus (February 12, 1950) is an American author, former US government prosecutor and former Army intelligence officer. He is a president of The Intelligence Summit and president of the Florida Holocaust Museum. Loftus also serves on the Board of Advisers to Public Information Research. He currently resides in St. Petersburg, Florida.
Son of a Boston firefighter, Loftus was born in Boston, Massachusetts and is a graduate of Boston College (BA, 1971) and Suffolk University (JD, 1977). He served in the U.S. Army from 1971 to 1974, attaining the rank of First Lieutenant. He began working for the US Department of Justice in 1977 and in 1979 joined their Office of Special Investigations, which was charged with prosecuting and deporting Nazi war criminals in the US. Loftus' now-expired Web site claimed, "As a young U.S. Army officer, John Loftus helped train Israelis on a covert operation that turned the tide of battle in the 1973 Yom Kippur War."
Loftus is the author and co-author of several books on Nazis, espionage, and similar topics including The Belarus Secret (1982), Unholy Trinity: How the Vatican's Nazi Networks Betrayed Western Intelligence to the Soviets (1992), The Secret War Against the Jews: How Western Espionage Betrayed the Jewish People (1994), Unholy Trinity: The Vatican, the Nazis, and the Swiss Banks (1998), America's Nazi secret: An Insider's History of How the United States department of Justice obstructed congress by: blocking congressional investigations into famous American families who funded Hitler, Stalin and Arab terrorists (2010). Although Loftus' first book, The Belarus Secret, is nonfiction, it was adapted into a TV-film, Kojak: The Belarus File (1985), with Telly Savalas.
The Israeli historian and Nazi hunter Efraim Zuroff described Loftus` The Belarus Secret as controversial and referred to Charles R. Allen Jr.´s review in Jewish Currents. Allen had called Loftus, in effect, a fraud and a liar. In addition the historian David Marwell described The Belarus Secret as the worst kind of amateur history. The book was also criticized by Vital Zayka, a fellow of the Center for Jewish History in New York City, who accused Loftus of falsification.
