Eugene Wesley Roddenberry (1921-91) was an American television and film producer best known for creating Star Trek: The Original Series, Star Trek: The Next Generation and Star Trek: The Motion Picture.
Apparently Roddenberry’s hands-on involvement with the popular Star Trek: The Next Generation dwindled away after the first few seasons. But TV execs kept his name in the credits, knowing it boosted credibility among fans.
Roddenberry was born into a Baptist family but came to reject religion, calling himself a humanist. This comes through in the Star Trek franchise, where religion is not eschewed but sometimes homogenized, suggesting that all paths are the same. A nice sentiment, this is an aspect of Star Trek that arguably oversimplifies. Otherwise, Star Trek productions tend to be intellectually satisfying.
Roddenberry also had a military background as a pilot. He flew commercially too. These experiences led him to envision a starship as a tight, military style outfit, with a clear line of command. After a commercial crash, he resigned from PanAm in 1945 and took up his career as a TV writer. The rest is history.
