Robert Anson Heinlein (July 7, 1907 â May 8, 1988) 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. His published works, both fiction and non-fiction, express admiration for competence and emphasize the value of critical thinking. His plots often posed provocative situations which challenged conventional social mores. His work continues to have an influence on the science-fiction genre, and on modern culture more generally.
Heinlein’s experience in the U.S. Navy exerted a strong influence on his character and writing. In 1929, he graduated from the Naval Academy with more or less the equivalent of a bachelor of arts in engineering (the Academy did not at the time confer degrees). He ranked fifth in his class academically but with a class standing of 20th of 243 due to disciplinary demerits. The U.S. Navy commissioned him as an ensign shortly after his graduation. He advanced to lieutenant junior grade in 1931 while serving aboard the new aircraft carrier USS Lexington, where he worked in radio communicationsâa technology then still in its earlier stages. He also served as gunnery officer aboard the destroyer USS Roper in 1933 and 1934, reaching the rank of lieutenant.
