Raoul,

You mentioned discovering science fiction from the 30's, the 40's and the 50's. One of my favorite "SF" authors is David Lindsay. His best book was also his first. The title is "A Voyage to Arcturus" and was published in 1920. The copyright has expired thus allowing it to be on-line. Its URL is:

It's not clear that "A Voyage to Arcturus" would translate well. Lindsay likes to make allegorical use of English and German word meanings. It's a little bit like polyphonic music. If you do opt to read "A Voyage to Arcturus", a word of caution: It starts out really slow (be patient). Things don't pick up until after you leave Scotland and reach the planet Tormance. Once you're there, you'll find the novel very interesting. If you do get through the novel, you may want to analyse it. Download the digital version of the novel and then search through it for significant word strings using a text editor. It's a bit like looking for Easter eggs. An example of this is discovering how Lindsay uses color. If you search the text for certain colors, you'll learn new things about the novel's meaning.
