Project MKUltra
Project MKUltra was a top-secret CIA project (c. 1953 - c.1973) in which the agency conducted hundreds of clandestine experiments, sometimes illegal, on mind control, information gathering and psychological torture. The exact extent of the program may be unclear due to most documents being destroyed.
The project was headed by the Jewish American Sidney Gottlieb, associated with various controversies, such as assassination attempts, which may or may not have been associated with project MKUltra.
