Inklings
"Properly speaking," wrote Warren Lewis, "the Inklings was neither a club nor a literary society, though it partook of the nature of both. There were no rules, officers, agendas, or formal elections." As was typical for university literary groups in their time and place, the Inklings were all male. 
Readings and discussions of the members' unfinished works were the principal purposes of meetings. Tolkien's "The Lord of the Rings", Lewis's "Out of the Silent Planet", and Williams's "All Hallows' Eve" were among the novels first read to the Inklings. Tolkien's fictional Notion Club (see "Sauron Defeated") was based on the Inklings. Meetings were not all serious; the Inklings amused themselves by having competitions to see who could read the notoriously bad prose of Amanda McKittrick Ros for the longest without laughing.
Arthur C. Clarke
During this time, Clarke corresponded with C. S. Lewis in the 1940s and 1950s and they once met in an Oxford pub, The Eastgate, to discuss science fiction and space travel. Clarke voiced great praise for Lewis upon his death, saying that the Ransom trilogy was one of the few works of science fiction that should be considered literature.
