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 and sometimes admitting his CIA connection while requesting samples of highly poisonous or physiologically active drugs.[^2]
