The [Office of Technical Service](/organizations/office-of-technical-service/) (OTS) was a division within the [CIA](/organizations/central-intelligence-agency/) 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](/programs/stargate-project/). [Ken Kress](/people/kenneth-a-kress/), an OTS engineer, was responsible for giving [SRI](/organizations/stanford-research-institute/) its first psi research contract in 1972. [Norm Everheart](/people/norm-everheart/) served as the chief of OTS's regional "tech base" in Athens before becoming a liaison to [Staff D](/organizations/staff-d/) and a key coordinator for Grill Flame taskings from the CIA's Operations Directorate.[^1]

[John McMahon](/people/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](/people/stanley-lovell/)'s Research and Development unit in the [OSS](/organizations/office-of-strategic-services/), 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](/people/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](/concepts/lsd/) peaked, [Sidney Gottlieb](/people/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 [MKULTRA](/programs/project-mkultra/). Gottlieb was aided by deputies including [Robert Lashbrook](/people/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](/organizations/army-chemical-corps/) and sometimes admitting his CIA connection while requesting samples of highly poisonous or physiologically active drugs.[^2]
