Fort Detrick was the Army's biological research center in [[Frederick, Maryland]], home to the [[Special Operations Division]] (SOD) and the larger U.S. biological warfare program. Built on the principle of concentric circles, with secrets concealed inside secrets, the base required not only the highest security clearance but a "need to know" authorization to enter the inner regions where SOD operated. To enter the SOD building itself, one needed an up-to-date shot card with anywhere from 10 to 20 immunizations.[^1]

### From Detrick Field to Camp Detrick

The installation began as Detrick Field, a small [[Maryland National Guard]] airfield established in 1931 and named for Frederick L. Detrick, an Army flight surgeon who had served in [[World War I]].[^2] In March 1943, with the United States at war, the War Department acquired the site and re-christened it Camp Detrick, making it the headquarters of a crash program to develop both defenses against and an offensive capability in [[biological warfare]]. The wartime laboratories, later formalized as the U.S. Army Biological Warfare Laboratories, pioneered work in biocontainment, decontamination, sterilization, and the production and purification of pathogens.[^2] In 1949 engineers completed a one-million-liter spherical aerosol test chamber, informally called the "8-ball," in which animals were exposed to airborne agents.[^2] The Army made the post permanent in 1956, redesignating Camp Detrick as Fort Detrick. The center remained the heart of the American offensive germ warfare effort from 1943 until 1969.[^2]

### The SOD-CIA partnership

Under the [[MKNAOMI]] program, the [[CIA]]'s [[TSS]] paid SOD about $200,000 a year to develop biological weapons for covert operations. [[Sidney Gottlieb]] and his TSS colleagues worked intimately with SOD scientists like [[Frank Olson]], [[Vincent Ruwet]], [[Benjamin Wilson]], and founder [[John Schwab]]. Twice a year, the SOD and TSS men held planning sessions at remote sites like [[Deep Creek Lodge]] in [[Western Maryland]], where they could brainstorm without interruption.[^1] The arrangement gave the CIA access to a covert arsenal that included [[shellfish toxin]] for rapid death, botulinum considered for use against [[Fidel Castro]], and pathogens chosen to appear indigenous to a target region, an approach raised in connection with the 1960 operation against [[Patrice Lumumba]] in the Congo. SOD also built the delivery hardware: aerosol generators, dart guns adapted from .45-caliber pistols, and devices concealed in everyday objects.[^1]

Three fatalities occurred at Fort Detrick during its 27-year history as a germ warfare center. When a Detrick employee died of [[anthrax]], Frank Olson told his wife the man had died of pneumonia, maintaining the code of secrecy that pervaded the installation.[^1] Olson himself had joined Detrick in 1943 and specialized in the airborne delivery of disease; he served briefly as acting chief of SOD in 1952 and 1953 before his death.[^1]

### 1969 termination and the shift to biodefense

On November 25, 1969, President [[Richard Nixon]] renounced the American offensive biological weapons program and ordered the existing stockpiles destroyed, a decision followed in February 1970 by an order extending the ban to toxins.[^3] SOD continued to manufacture and stockpile bacteriological agents for the CIA until that point.[^1] Detrick's mission shifted to defensive medical research: the U.S. Army Medical Research Institute of Infectious Diseases ([[USAMRIID]]) was established at the post in 1969 to develop countermeasures against biological threats, and in 1972 a portion of the grounds was turned over to the [[National Cancer Institute]] for cancer and, later, AIDS research.[^2] The dismantling of the offensive program did not end the CIA's involvement: in 1975 the [[Church Committee]] revealed that the Agency had retained a cache of shellfish toxin taken from Detrick in defiance of the 1970 destruction order.[^3]
