Margaret Thaler Singer (1921–2003) was a renowned expert in the subject of mind control. Trained as a clinical psychologist, with a Ph.D. from the University of Denver, she conducted research on troops who returned from the Korean War to determine the psychological stresses they had undergone. Singer became interested in Peoples Temple shortly before the deaths in Jonestown in November 1978. She was asked to work with former members at the Human Freedom Center, an organization established to help people leave the Temple. Most of the tapes in the Margaret Singer collection comprise shortwave radio conversations between Peoples Temple members in Jonestown, Georgetown, and San Francisco. These tapes were made by members of the Concerned Relatives, an oppositional group that met informally in 1976 and became more organized in 1977. To understand these secret radio messages it will be helpful to have the “Peoples Temple Code Book” handy: (http://jonestown.sdsu.edu/?page_id=13221 ).

Reports highlight Concerned Relatives activities on April 11th and May 10th, 1978, and include interviews with members of the Concerned Relatives. http://www-rohan.sdsu.edu/nas/streaming/dept/scuastaf/collections/peoplestemple/SingerTapes/mp3/Tape01.mp3
