This is a collection of Heinlein’s SF stories, other stories, and articles, beginning with his first SF story in 1939, and including stories & articles through the 1970s.  Most have been previously published.  In this collection, published in 1980, Heinlein provides a foreword to each story and article, to place them in context, both  in terms of personal circumstances, thoughts, and the broader context of science & technology, WWII, and the development and  use of catastrophic weapons of war.
The underlying themes of science, technology, and war, and  how we humans respond  to these, make Heinlein's stories and articles   timeless, and very relevant to the current times.

Robert A. Heinlein
Robert Anson Heinlein was an American science fiction writer. Often called "the dean of science fiction writers", he was one of the most popular, influential, and controversial authors of the genre. He set a high standard for science and engineering plausibility and helped to raise the genre's standards of literary quality. He was one of the first writers to break into mainstream, general magazines such as The Saturday Evening Post, in the late 1940s, with unvarnished science fiction. He was among the first authors of bestselling, novel-length science fiction in the modern, mass-market era. For many years, Heinlein, Isaac Asimov, and Arthur C. Clarke were known as the "Big Three" of science fiction. ([Source](http://en.wikipedia.org/wiki/Robert_A._Heinlein).)
