"The best way to make dreams come true is to wake up."
Nichelle Nichols was the first African-American woman to play a lead role on television, Communication Officer Lieutenant Uhura on "Star Trek".
Shortly after giving notice to Gene Rodenbury that she wanted to leave the show, she had a visit from "a fan", who turned out to be none other than Dr. Martin Luther King. "I am the biggest Trekkie on the planet, and I am lieutenant Uhura’s most ardent fan" he told her, and went on to say:
"Do you not understand what God has given you? You have the first important non-traditional role, non-stereotypical role. You cannot abdicate your position. You are changing the minds of people across the world, because for the first time, through you, we see ourselves and what can be."
In 1992 Mae Jemison became the first African-American woman to travel into space, aboard the Space Shuttle Endeavor. She had served in the Peace Corp before that, and after NASA was a professor at Cornell and Dartmouth before founding her own technology research company in 1999.
Ms. Jemison has said that her inspiration for joining NASA was Nichelle Nichols' portrayal of Lieutenant Uhura.http://www.pbs.org/wnet/pioneers-of-television/pioneering-people/nichelle-nichols/https://en.wikipedia.org/wiki/Mae_Jemison
