"Mr. Spaceship" by Philip K. Dick is a science fiction novelette first published in 1953. Humanity wages a losing war against the Yuks, aliens who power their technology with living organisms rather than machines. When researcher Philip Kramer and his team create a spaceship controlled by a human brain—his dying professor's—they believe they've found the solution. But the professor has other plans, seizing control of the vessel to pursue his own vision for humanity's future. (This is an automatically generated summary.)
