Heinlein, Robert A.

Robert Anson Heinlein (/ˈhaɪnlaɪn/;[2] [3] [4]  July 7, 1907 – May 8, 1988) was an Americanscience-fiction writer. Often called the "dean of science fiction writers",[5]  he wrote sometimes controversial works which continue to have an influential effect on the science-fiction genre, and on modern culture more generally.

Heinlein became one of the first American science-fiction writers to break into mainstream magazines such as The Saturday Evening Post in the late 1940s. He was one of the best-selling science-fiction novelists for many decades, and he, Isaac Asimov, and Arthur C. Clarke are often considered the "Big Three" of English-language science fiction
