| Philip Zack |
Lt. Col. Dr. Philip M. Zack is a microbiologist who worked at the U.S. Army's Medical Research Institute for Infectious Diseases in Fort Detrick, Maryland.
“Zack left Fort Detrick in December 1991, after a controversy over allegations of unprofessional behavior by Zack, Dr. Marian Rippy, [lab technician] Charles Brown and others who worked in the pathology division. They had formed a clique that was accused of harassing the Egyptian-born Assaad, who later sued the Army, claiming discrimination.”

“Dr. Zack left Fort Detrick in December 1991 amid allegations of unprofessional conduct. The Jewish scientist and others were accused of harassing their co-worker, Dr. Ayaad Assaad, until the Egyptian-born American scientist quit, according to an article in Connecticut’s The Hartford Courant, the country’s oldest newspaper in continuous publication. Dr. Assaad sued the Army, claiming discrimination after Zack’s badgering.
Although Dr. Zack was let go, he returned frequently to visit friends, and used the Fort Detrick laboratories for “off-the-books” work after hours. After reports of missing biological specimens — including anthrax, ebola and the simian AIDs virus — came to light, as well as reports of unauthorized research, a review of surveillance camera tapes recorded Dr. Zack entering the lab late on the night of Jan. 23, 1992, according to The Hartford Courant report. He was let in that night by Marian Rippy, a lab pathologist and close friend of Zack’s, although she now says she has no memory of the evening. She did say that Zack occasionally visited and that other friends let him in.
Soon after the 9/11 attack, a long, typed anonymous letter was sent to Quantico Marine Base accusing the long-suffering Assaad, Zack’s victim in 1991, of plotting terrorism. This letter was received before the anthrax letters or disease were reported. The timing of the note makes its author a serious suspect in the anthrax attacks. The sender also displayed considerable knowledge of Dr. Assaad, his work, his personal life and a remarkable premonition of the upcoming bioterrorism attack.
After interviewing Assaad on Oct. 2, 2001, the FBI decided the letter was a hoax. While major newspapers noted that an anonymous letter had accused Dr. Assaad of bioterrorism, none followed up on it after his innocence was established. Zack’s name never surfaced again as one of the 30 suspects.
When the Washington Report on Middle East Affairs asked Barbara Hatch Rosenberg, Ph.D., a biological arms control expert at the State University of New York, if the allegations regarding Dr. David Hatfill now took the heat off Lt. Col. Philip Zack, she replied, “Zack has NEVER been under suspicion as perpetrator of the anthrax attack.”
It is hard to believe that, with his connection to Fort Detrick, Dr. Zack is not one of the 20 to 50 scientists under intense investigation.
Another person not naming names is New York Times reporter Nicholas D. Kristof. In a series of articles published on July 2, 12, and 19, however, he called the anthrax perpetrator “Mr. Z” (not “Mr. H”). Kristof’s description of “Mr. Z” sounds very much more like Dr. Zack than Dr. Hatfill.
The New York Times journalist reported that “Mr. Z” was caught with a girlfriend after hours in Fort Detrick. According to Kristof, “Mr. Z” talked about the importance of his field and his own status in it, and often used the B’nai B’rith attack as an example of how anthrax attacks might happen. He also “had a penchant for dropping Arab names” when he discussed the possibility of anthrax attacks.
Is the anthrax culprit, or “Mr. Z,” actually Dr. Zack or Dr. Hatfill, or another undisclosed scientist? Is Dr. Hatfill being framed while Dr. Zack stays out of the spotlight? Will the investigation simply peter out without an arrest? Are the U.S. government and the media engaging in a shameful cover-up?”

“An internal Army inquiry in 1992 would reveal that one employee, Lt. Col. Philip Zack, had been caught on camera secretly entering the lab to conduct “unauthorized research, apparently involving anthrax,” the Hartford Courant would later report. Despite this, Zack would continue to do infectious disease research for pharmaceutical giant Eli Lilly and would collaborate with the U.S. National Institute of Allergy and Infectious Disease (NIAID) throughout the 1990s. The Courant had also noted that: “A numerical counter on a piece of lab equipment had been rolled back to hide work done by the mystery researcher [later revealed to be Zack], who left the misspelled label ‘antrax’ in the machine’s electronic memory.” The Courant’s report further detailed the extremely lax security controls and chaotic disorganization that then characterized the U.S. Army Medical Research Institute of Infectious Diseases (USAMRIID) lab in Fort Detrick.”
