Future History (novel)

The Future History, by Robert A. Heinlein, describes a projected future of the human race from the middle of the 20th century through the early 23rd century. The term Future History was coined by John W. Campbell, Jr. in the February 1941 issue of Astounding Science Fiction. Campbell published an early draft of Heinlein's chart of the series in the March 1941 issue.

Heinlein wrote most of the Future History stories early in his career, between 1939 and 1941 and between 1945 and 1950. Most of the Future History stories written prior to 1967 are collected in The Past Through Tomorrow, which also contains the final version of the chart. That collection does not include Universe and Common Sense; they were published separately as Orphans of the Sky.

The Future History was nominated for the Hugo Award for Best All-Time Series in 1966, along with the Barsoom series by Edgar Rice Burroughs, the Lensman series by E. E. Smith, the Foundation series by Isaac Asimov, and The Lord of the Rings series by J. R. R. Tolkien, but lost to Asimov's Foundation series.

For the most part, The Past Through Tomorrow defines a core group of stories that are clearly within the Future History series. However, Heinlein scholars generally agree that some stories not included in the anthology belong to the Future History series, and that some included are only weakly linked to it.

James Gifford adds Time Enough for Love, which was published after The Past Through Tomorrow, and also "Let There Be Light", which was not included in The Past Through Tomorrow, possibly because the collection editor disliked it or because Heinlein himself considered it to be inferior. However, he considers Time Enough for Love to be a borderline case. He considers The Number of the Beast, The Cat Who Walks Through Walls, and To Sail Beyond the Sunset to be too weakly linked to the Future History to be included.
