Leary, TimothyLea‧ry, Tim‧o‧thy /ˈlɪəri, ˈtɪməθi/ 
(1920–96) an American writer and psychologist who believed that controlled use of the drug LSD could change people’s lives in a positive way. He is known for saying ‘Turn on, tune in, drop out’. In 1963 he was forced to leave his job as a psychology professor at Harvard University because he had been doing experiments with LSD on students. He continued his experiments at a large house in New York called Millbrook, but was put in prison. The Weather Underground Organization, a communist terrorist group, helped him to escape, but he was later caught in Switzerland and taken back to the US.
