Nat Schachner, in Astounding

Research History
Mike Christie found a 1943 cite from Fritz Leiber.
Kevin Wald then found a reference to a May 1938 story called "Niedbalski's Mutant", by Spencer Lane, and Mike Christie then found more citations in that story.
Sue Surova found a cite in a reprint of Edmond Hamilton's "He That Hath Wings"; the OED verified this in the July 1938 original in "Weird Tales".
Cory Panshin located a reference in John Campbell's editorial in the January 1938 Astounding. This usage is figurative, rather than direct, and we would still like other cites antedating the Hamilton or Lane stories.
Jesse Sheidlower found a 1934 cite from Nat Schachner, and a 1936 cite from Stanley Weinbaum, both in Astounding.

Earliest cite in OED2 was 1954 in the sf sense: updated June 2003 to 1938.
