Foundation series
In 1937, John W. Campbell became editor of "Astounding Science Fiction", an event which is sometimes considered the beginning of the Golden Age of Science Fiction, which is characterized by stories celebrating scientific achievement and progress. In 1942, Isaac Asimov started his Foundation series, which chronicles the rise and fall of galactic empires and introduced psychohistory. The series was later awarded a one-time Hugo Award for "Best All-Time Series." The "Golden Age" is often said to have ended in 1946, but sometimes the late 1940s and the 1950s are included.
