In the late 1970’s, LSD was big in Cambridge University’s radical academic fringe, inspired by LSD pioneer Timothy Leary. He had a strong belief that the drug broadened the mind and could transform society and make it better for all of us. Henry Todd got very much into this scene and then started his own LSD lab, producing huge quantities of the stuff. In the episode of the UK True Crime Podcast, I look at the undercover police operation ‘Operation Julie’ soon had Henry Todd and others making and selling LSD under surveillance, and how Todd later made the unusual move into high altitude mountaineering.
