In 1940 and 1941, Heinlein was pumping out so many stories that half of them appeared under pseudonyms. Some of them were stories now considered classics, and examples of purest Heinleinesque writing.
The question I have is, how open a secret was it that Anson MacDonald (and to a lesser extent Caleb Saunders, and Lyle Monroe, and John Riverside) was Heinlein? If no one (or only a tiny coterie) knew it then, when did it become common knowledge?
Patterson doesn’t do more than mention pseudonyms. So I researched the known chronology.
Two MacDonald stories were run under that name in 1946 anthologies, alongside stories credited to Heinlein. But in 1948 Fantasy Press published Beyond That Horizon under the Heinlein name and in 1949 Gnome Press published Sixth Column as by Heinlein. Did heads explode, or did fans just nod and say, it’s about time?
While I’m looking at it, can anyone explain Campbell’s strategy in doing this? I get that Lyle Monroe was used for low-end stories for lesser markets. I sorta get using a pseudonym for Unknown - keep the sf persona for Astounding - which explains running “The Unpleasant Profession of Jonathan Hoag” as by John Riverside. But that makes publishing “Waldo” under the MacDonald name weird. “Elsewhere” supposedly was so different that it required the Caleb Saunders pseudonym.
Still doesn’t explain 1941. Heinlein stories appeared 14 times, seven as Heinlein, six as MacDonald, once as Saunders. Heinlein had already appeared six times with five stories in 1940; he was a rising star. So why not promote his name incessantly? Campbell didn’t have to bury Heinlein because of lack of space - those fourteen appearances were in only eight issues. Nothing under any name was published in April, June, November, or December. Even odder: The Heinlein name never appeared again in Astounding until 1949 (except for a review). Yet three Anson MacDonald stories appeared in four 1942 issues, March, May, June, and August. That meant four months in a row with nothing by Heinlein at the peak of his introductory splash. I don’t get it.
Why? I know the prejudice against running more than one story by a given name was endemic in magazines generally. Campbell might have thought the well would never run dry, except that in his letters Heinlein was always complaining of not having new ideas. He wasn’t running other authors under pseudonyms to any extent - maybe not at all - from looking at the 1940-1942 contents pages. Doing this for Heinlein seems counterproductive at best.
