A physicist at the RAND Corporation who advised Gene Roddenberry on scientific and technical matters while the first Star Trek pilot, The Cage, was being written in 1964.
Harvey P. Lynn Jr. was a physicist with the RAND Corporation, the research organisation in Santa Monica, California. In 1964 Gene Roddenberry engaged him, for a nominal fee, as a technical adviser on the first Star Trek pilot, The Cage.
Lynn read Roddenberry's outlines and script drafts and replied with detailed notes on astronomy, spacecraft, weapons, medicine and terminology. Some were small points of consistency: he observed, for example, that the slight build of the Talosians did not suit a planet with gravity higher than Earth's, and the figure in the script was lowered.
His correspondence helped to give the series its habit of grounding its inventions in plausible science, a practice later continued with other consultants.
