Robert A. Heinlein
Robert A. Heinlein was an American author of science fiction, considered to be part of the “Big Three” in the genre along with Isaac Asimov and Arthur C. Clarke . Some of his work is also considered part of the fantasy genre as well. Heinlein wrote about space exploration as if it were a very real possibility. Other common themes in his work included individualism, non-conformity and free love. Because much of his work was written during the Civil Rights Movement, he would often imply a major character was not white or he would use an alien as a metaphor for another human race (in a positive manner).
