Scrooge- Astounding is the ONE! when Amazing & Wonder paled in early 1930s Astounding took over in the story department with writers like John W Campbell (who would become editor and launch 'modern SF'), Stanley Weinbaum, Jack Williamson, and Clifford D Simak producing great stuff. When Campbell took over editor in '39 we start to get Heinlein, Sturgeon, Asimov, Van Vogt, etc. I love Simak- his 'Cosmic Engineers' is a 1939 classic, as is his 1964 Hugo winner 'Way Station'. perhaps the short stories of the era are even better: Simak's 1944 'Desertion' at 10 pages or so is a KEY to 'Avatar'. been avid fan 50 yrs let me know if you need author suggestions.
