More than a half-century after it first debuted, Star Trek: The Original Series is still lauded for its contributions to popular culture. One of the most progressive elements of the series is the diversity of the crew on the USS Enterprise. Spock may have been an alien, but audiences of the 1960s were more surprised to see women and people of color on the bridge. One of those characters, Hikaru Sulu, was named very carefully by series creator Gene Roddenberry as part of his aspirational vision for the future.
