Each story gets my mind working.
Travel By Wire!, 1937
Years ago I read a short story by Stephen King that now seems like a revisiting of this idea, but I can't remember the name of the story. In Travel By Wire, the scientists run a guinea pig through the teleport machine and it immediately dies of shock. In Stephen's story, people are sent through the machine sedated and asleep, so that they don't consciously experience the shock of traveling. Then, of course, one character defies the warning and goes through fully awake. Chaos ensues, et cetera.
Ah yes. It was called "The Jaunt".
How We Went To Mars, 1937
Cute, in a proto-steampunk sort of way. The first people to visit Mars are a bunch of doddering old British chappies who like to smoke and play cards. Why not!
Retreat From Earth, 1938
No wikipedia entry about this one. I'm not surprised, it's not nearly as fun as the previous two.
