The textual history of Hugo Gernsback's novel Ralph 124C 41+: A Romance of the Year 2660

I just started reading SF author, editor, and critic
Gary Westfahl’s ambitious essay entitled “Evolution of Modern Science Fiction: The Textual History of Hugo Gernsback's Ralph 124C 41+,” published in the March 1996 issue of Science Fiction Studies.

A serious piece of scholarship, Westfahl’s essay studies five editions of Ralph 124C 41+: A Romance of the Year 2660 (original 1911-12 serial published in Modern Electrics magazine; first edition of novel, published in 1925 by Stratford Company; 1929 version published in Winter 1929 issue of Amazing Stories Quarterly magazine; second edition of novel, published in 1950 by Frederick Fell, Inc.; 1958 novel published by Fawcett Crest) and concludes that Hugo Gernsback’s Mars and Martians have their roots in To Mars via the Moon (1911),
a “scientific novel” written by Mark Wicks and one which Gernsback likely read and reviewed in August 1911.
