Talking about Time & Dimensions, and a fantastic author from the Golden Age, one should mention the wonderful
John Wyndham, who was a very natural progression on from Verne and Wells. My apologies if he has already been mentioned. I did not see him in the first few pages of this topic, and it has now become a lot to read and gone off on various tangents, some that interest me and some that don't.
John Wyndham stood out almost alone at that time, in being from England and not America, yet writing great Science Fiction ... not common amongst Brits at the time.
