Central Intelligence Agency Directorate of Science & Technology

The Directorate of Science and Technology is the branch of the United States Central Intelligence Agency (CIA) charged with developing and applying technology to advance the United States intelligence gathering.

On December 31, 1948, the CIA formed the Office of Scientific Intelligence (OSI), by merging the Scientific Branch in the Office of Reports and Estimates with the Nuclear Energy Group of the Office of Special Operations.

In 1962, the CIA formed the Deputy Directorate of Research (DDR), headed by Herbert Scoville. Under it was the newly formed Office of Special Activities, along with the Office of ELINT and the Office of Research and Development, which were quickly integrated into the DDR. However, the OSI remained part of the Directorate of Operations.

In 1963, Scoville resigned, frustrated by the unwillingness of other departments to transfer their responsibilities.Director of Central Intelligence John McCone asked Albert Wheelon to replace Scoville in the renamed Deputy Directorate of Science and Technology. The OSI was transferred to the Deputy Directorate of Science and Technology, along with the Office of Computer Services.

In 1965, the Directorate was renamed again, to the Directorate of Science and Technology (DS&T), and in 1966 Carl Duckett succeeded Wheelon as the Deputy Director for Science and Technology.

In April 1973, DCI James Schlesinger transferred the Technical Services Division of the Operations Directorate to the DS&T, where it would be renamed the Office of Technical Services (OTS). Its primary focus was technical support of CIA case officers in the field, including development of exotic weapons and eavesdropping devices and production of forged documents. It developed a poison pen and exploding seashells in an effort to assassinate Fidel Castro.
