During WWII, a group of science fiction writers, Robert Heinlein & Isaac Asimov prominent among them, were involved in a classified project for the US government.

Isaac Asimov mentioned this project in his autobiography In Memory Yet Green. There are also some comments on it in the posthumous Heinlein tribute/collection Requiem; several people are quoted to the effect that Heinlein never said exactly what he did because it had not been declassified.

Have the details about this project and these writers’ involvement since been declassified? If not, are there any hints as to what the project entailed?

  • Hmm... one of the top 5 Google hits for "asimov heinlein classified project wwii" ends up on Wiki "Nazi UFOs" page. Coincidence? :) Jun 20, 2012 at 22:49

    asimovonline FAQ has only this: "He [Asimov] worked as a junior chemist at the Philadelphia Navy Yard from May 1942 to October 1945, together with fellow science fiction authors Robert Heinlein and L. Sprague de Camp" Jun 20, 2012 at 23:12

    Do you have a reference for this?

    @Pureferret: look in Asimov's first autobiographical volume, In memory yet green, which writes about this.

There are actually plenty of details about their work, for example in Learning Curve, Heinlein's authorized biography. It may have been classified at one time (most war operations were as a matter of course) but it's not any more. De Camp and Asimov wrote about it too.

Robert Heinlein, L. Sprague De Camp, and Isaac Asimov during World War 2
L to R: Heinlein, De Camp, Asimov

There have been rumors that the group were somehow tied to the apocryphal "Philadelphia Experiment". De Camp responded to this question himself and said basically: that's a great story but he worked on testing hydraulics and de-icers and equally mundane problems

According to a couple chapters of Heinlein's book, they worked at the Aeronautical Materials Lab at Philadelphia Naval Yard. Their work included a "high altitude pressure suit" (an early space suit), and a "Cold Room" (a cryogenic hypobaric chamber) to test exposure to extreme cold and low oxygen. Heinlein was also the personnel manager (where he broke policy by hiring female engineers) and worked on "mechanical problems of Plexiglas aircraft canopies" (where he got in trouble for refusing to falsify data). Heinlein was officially retired Navy, De Camp was a Navy reservist, and Asimov was a civilian contractor (though he was later drafted in September 1945). Forry Ackerman was involved too, as an Army enlisted man.

But the most important work they did was not something they directly worked: they contributed ideas to and consulted on the development of the CIC or Combat Information Center - the today-familiar Operations Room of a combat vessel. Their consultation was regarded as critical to its development. The idea came right out of, and is still part of, science fiction and was implemented in reality by the US Navy during WWII. So it's a funny bit of history -- the Operations Center came out of Sci-Fi as related by Heinlein/Asimov/deCamp, got implemented for real in the Navy, and now the Ops Centers in modern Sci-Fi are directly informed by the real-life ones, full circle! But it's a stretch to say they worked on it.

Basically the truth was this: Heinlein, De Camp, and Asimov were friends and colleagues, the war meant they had to either serve the US professionally or get drafted, and they were all educated men who could do useful engineering work. So Heinlein worked hard to get his friends and colleagues jobs in a stateside engineering center rather than on the front. Since they were very bright people with good scientific knowledge, their contributions were useful though not mysterious nor earth-shattering.

There was a novel released last year, The Astounding, The Amazing, The Unknown, which fictionalizes and sensationalizes the whole idea but in not in fact true :)

You might also check out the Cleve Carmill Affair (1) (2), which involved Heinlein/Asimov/DeCamp peripherally, as well as John Campbell. That's when the US Gov't was convinced that Carmill and Campbell had been stealing nuclear secrets.....

    There was no chance of Heinlein being drafted. He could not get himself declared physically able to serve, his first choice resuming his service as a naval officer. I don't think de Camp or Asimov needed that particular job to avoid the draft either.

  • In the excellent "Information at Sea: Shipboard Command and Control in the U.S. Navy, from Mobile Bay to Okinawa" by Timothy S. Wolters (Johns Hopkins University Press, 2013), we read on page 219-220: "A few months after World War II ended, the Office of the Chief of Naval Operations decided to publish a confidential synopsis of the CIC "for the uninitiated who want information on the what and why" of the navy's relatively new shipboard facility. OPNAV described the Combat Information Center as "a weird and eerie jungle of electronic gear, illuminated tables, shining dials and gadgets," with Apr 6, 2021 at 11:25
  • "officers and enlisted personnel ... wearing earphones and talking strange jargon into microphones, telephones, and squawk boxes that seem to be constantly flashing red light." Employing a touch of hyperbole, OPNAV claimed the CIC made "Flash Gordon look like a piker and Buck Rogers an anachronism" ("CIC Yesterday and Today", C.I.C., November 1945, 3.) Indeed, to many individuals the CIC must have seemed like something from the future. Perhaps even Caleb Laning thought so; at one point during the war, he suggested that the science fiction of his good friend Apr 6, 2021 at 11:25
  • and Naval Academy classmate Robert Heinlein had influenced his thinking, writing in a letter to Heinlein that the "basic ideas" of the CIC were "very similar to some of [your Astounding Science Fiction] 'brain machine' ideas." Apr 6, 2021 at 11:25

    The link between science fiction and actual science is pretty damn strong. Mentioned that Szilard was inspired by Wells who first spoke of atomic bombs although probably it was the other way around with bombs specifically. But how many scientists and engineers were inspired by scifi in their youth? How many future astronauts watched Star Trek or Forbidden Planet (could it literally be that no astronaut did NOT see Forbidden Planet? i bet maybe every single one did. i sure doubt that any missed reading Wells and Verne,)
