The Chief Medical Officers who served aboard the flagship of the United Federation of Planets in Star Trek: The Original Series, Star Trek: The Next Generation, and Star Trek: Enterprise are also among the most popular characters in the franchise, and they have inspired many in the real world to pursue the field of medicine and become doctors themselves.
