Heinlein’s life story is fascinating and well documented. Stranger in a Strange Land was just one of his many influential works, and the world of literature is fuller because of his creations.

Starship Troopers was published after his marriage to a woman, Virginia, who significantly affected his political and social worldviews. That’s not speculation, that’s from the man himself. By the end of his life, he had reversed almost all of his early progressive opinions in his writings, which often included arguments in favor of xenophobia, eugenics, and fascism. If you read his writings in chronological order, it’s like watching a brain literally rot with time.
