The [[Office of Technical Service]] (OTS) was a division within the [[Central Intelligence Agency|CIA]] responsible for technical assistance to spying and covert-action operations. It was previously known as the Technical Services Division (TSD). OTS was often referred to as the "Q Branch" of the CIA, akin to the gadget-strewn division in the James Bond films.[^1]

OTS played a significant role in the early funding and management of the CIA's psi research, including the [[Stargate Project|Stargate Project]]. [[Kenneth A. Kress|Ken Kress]], an OTS engineer, was responsible for giving [[Stanford Research Institute|SRI]] its first psi research contract in 1972. [[Norm Everheart]] served as the chief of OTS's regional "tech base" in Athens before becoming a liaison to [[Staff D]] and a key coordinator for Grill Flame taskings from the CIA's Operations Directorate.[^1]

[[John McMahon]], the CIA's deputy director for operations, was also the head of OTS, indicating the importance of this office in technical and covert operations, including those involving psychic intelligence.[^1]

### Technical Services Staff and the OSS Lineage

In its earlier incarnation as the Technical Services Staff (TSS) in the 1950s and 1960s, the office was the lineal descendant of [[Stanley Lovell]]'s Research and Development unit in the [[Office of Strategic Services|OSS]], furnishing the gadgets of covert operations: false papers, bugs, taps, suicide pills, disguises, invisible inks, and concealment devices. It was headed at various times by [[Willis Gibbons]], a former [[U.S. Rubber Company]] executive, and later by [[Seymour Russell]].[^2]

### The Chemical Division

Within TSS a Chemical Division handled the use of chemicals and germs against specific people. From 1951 to 1956, the years when the CIA's interest in [[LSD]] peaked, [[Sidney Gottlieb]] headed this division, and for most of the years until 1973 he oversaw TSS's behavioral programs from one post or another, including [[Project MKUltra|MKULTRA]]. Gottlieb was aided by deputies including [[Robert Lashbrook]] and staff such as [[Henry Bortner]], David Rhodes, and [[Ray Treichler]], who handled TSS's liaison with pharmaceutical companies, sometimes claiming to be from the [[Army Chemical Corps]] and sometimes admitting his CIA connection while requesting samples of highly poisonous or physiologically active drugs.[^2]
