[citation needed] When the United States entered World War I in 1917, Meek joined the military as a chemist and ordnance expert.

[citation needed] Meek sold his first fiction story, "Taming Poachers", to Field and Stream, where it appeared in September 1928.

He utilized many contemporary science fiction tropes, e.g. the notion that atoms were miniaturized solar systems in his stories "Submicroscopic" and "Awlo of Ulm".

In the first issue of Astounding Science Fiction in 1930, its editor Harry Bates listed Meek among "some of the finest writers of fantasy in the world", alongside Murray Leinster, Ray Cummings and others.

[2] However, Meek's stories were crudely executed and the higher standards introduced with the Golden Age of Science Fiction soon made them of strictly historical interest.
