Professor Jameson

Professor Jameson is a character created by J. Neil Jones, a pulp writer of the early 20th century, who was working for hire and hence had no legal right to the character. He appeared in the pulp magazine Amazing Stories in early 1931, and the series that followed was the most famous of its kind to ever emerge from the pulp magazine era.

Character Description
Professor Robert Jameson, after his death, left instructions to his nephew Douglas Jameson: he stole his uncle's body from the family crypt and placed it in a rocket that the two men had built prior to his death. He then launched the rocket into orbit around the Earth, where it remained for hundreds of thousands of years. Because Douglas Jameson had pumped out the air from inside the rocket, his uncle's corpse remained perfectly preserved for forty billion years, protected by a deflector field invented by the Professor. Finally, the Zoromes - inhabitants of another world who had placed their brains in completely mechanical bodies - found the rocket and negated its force field. Pulling the Jameson Satellite into their ship, the Zoromes recovered his body, removed his brain and restored it to life, then transposed it into one of their artificial bodies. As a Zorome machine man, Professor Jameson has no need for food or drink, and communicates using telepathy, which was bestowed on him through the Zoromes' medical science. He goes by the new designation not of Professor Jameson but of 21MM26, because Zoromes adopt a numerical designation when they change form. In fact, the Zoromes also supplement their forces by implanting the brains of three aliens known as Tripeds into machine man bodies, as they often do with people of other races that they encounter on their travels, which can last many hundreds of years.
