According to Wikipedia, Raymond Zinke Gallun (rhymes with "balloon") "was born in Beaver Dam, Wisconsin. He lived a drifter's existence, working a multitude of jobs around the world in the years leading up to World War II." At least a few people have said that The Planet Strappers is an underrated science fiction novel.
The Planet Strappers started out as The Bunch, a group of student-astronauts in the back room of a store in Jarviston, Minnesota. They wanted off Earth, and they begged, borrowed and built what they needed to make it. They got what they wanted–a start on the road to the stars–but no one brought up on Earth could have imagined what was waiting for them Out There!
