In 1966, the world was introduced to the world of Star Trek. Viewers watched as Captain Kirk, Mr. Spock and crew of the starship Enterprise sought to "explore strange new worlds, to seek out new life and new civilizations, to boldly go where no man has gone before." The show was created by Gene Roddenberry, and though he is now remembered as a creative powerhouse, he didn't have the most traditional path to a career in television.

Before Star Trek, Roddenberry was an Air Force pilot during World War II. After the war ended, he flew planes for Pan American World Airways. He was a Los Angeles police officer for eight years, and during his time at the LAPD, he was a speechwriter for the city's police chief and a technical advisor for popular legal shows of the time such as Dragnet and Mr. District Attorney, where he got his start as a scriptwriter.

Roddenberry's vision of the future was a progressive and hopeful one that was built on a philosophy of collaboration, exploration and a respect for a diversity of perspectives. Fifty years, five television series (with a sixth to come in 2017) and 12 films later, clearly it was a vision that has resonated with many.
