In 1952, von Braun first published his concept of a crewed space station in a "Collier's Weekly" magazine series of articles titled "Man Will Conquer Space Soon!". These articles were illustrated by the space artist Chesley Bonestell and were influential in spreading his ideas. Frequently, von Braun worked with fellow German-born space advocate and science writer Willy Ley to publish his concepts, which, unsurprisingly, were heavy on the engineering side and anticipated many technical aspects of space flight that later became reality.
