Before Dr. Ronald E. McNair was an astronaut, he was a little boy who lived in Lake City, South Carolina. And the Lake City library did not allow African Americans to borrow books. Nine-year-old McNair refused to leave the library and the police were called.
McNair was the second African American astronaut in space. He held a Ph.D. in physics from MIT and was a specialist in laser physics. What a loss it would have been if he had never been allowed to borrow those books.
