About Robert A. Heinlein
Robert Anson Heinlein was an American science fiction author, aeronautical engineer, and naval officer. Sometimes called the "dean of science fiction writers," he was among the first to emphasize scientific accuracy in his fiction, and was thus a pioneer of the subgenre of hard science fiction.
Some of his most influential works include "Stranger in a Strange Land," "Starship Troopers," and "The Moon is a Harsh Mistress."
