Works of American science-fiction writer Robert Anson Heinlein include Stranger in a Strange Land (1961) and The Moon Is a Harsh Mistress (1966). People often call this novelist "the dean of science fiction writers", one of the most popular, influential, and controversial authors of "hard science fiction." He set a high standard for science and engineering plausibility and helped to raise the standards of literary quality of the genre. He was the first science-fiction writer to break into mainstream, general magazines such as The Saturday Evening Post, in the late 1940s. He was also among the first authors of bestselling, novel-length science fiction in the modern, mass-market era. Also wrote under Pen names: Anson McDonald, Lyle Monroe, Caleb Saunders, John Riverside and Simon York.

Philip K. Dick was born in Chicago in 1928 and lived most of his life in California. In 1952, he began writing professionally and proceeded to write numerous novels and short-story collections. He won the Hugo Award for the best novel in 1962 for The Man in the High Castle and the John W. Campbell Memorial Award for best novel of the year in 1974 for Flow My Tears, the Policeman Said. Philip K. Dick died on March 2, 1982, in Santa Ana, California, of heart failure following a stroke. In addition to 44 published novels, Dick wrote approximately 121 short stories, most of which appeared in science fiction magazines during his lifetime. Although Dick spent most of his career as a writer in near-poverty, ten of his stories have been adapted into popular films since his death, including Blade Runner, Total Recall, A Scanner Darkly, Minority Report, Paycheck, Next, Screamers, and The Adjustment Bureau. In 2005, Time magazine named Ubik one of the one hundred greatest English-language novels published since 1923.
