In the 1992 film Lawnmower Man we see:

Angelo confronts Jobe, who captures him and declares his plan to reach the final stage of evolution by becoming "pure energy" in the VSI computer mainframe, and from there reach into all the systems of the world. He promises his "birth" will be signalled by every telephone on the planet ringing simultaneously.

There is a scene in Superman 3:

it's about Richard Pryor as a genius computer nerd who is manipulated into designing a supercomputer in a massive cave. The supercomputer became sentient and started fighting Superman and the other people who tried to disable it. One of them, the villain's sister Vera, is grabbed by the supercomputer's energy beams and pulled into the computer, where the machine transforms her into a robot.

What was the first sci-fi reference to one's life/being leaving the biological and becoming part of the machine/program?

ie what I'm looking for is where someone's mind is uploaded to the computer. (If they become a robot that is part of the computer/machine's being - that counts too). The earliest ones will definitely be written, not necessarily movies. I’m not talking about a brain transplant to a robot exclusively but living on as part of the computer program or extension of the computer.

(I removed the embedded images as they were considered confronting)

    Does "Tron" count? It predates Superman 3 by a year, and Flynn is downloaded into a computer, although neither voluntarily nor permanently. – Eike Pierstorff Jul 29 '20 at 9:43
  • This similar question mentions the tin man of "The Wizard of Os", who use to be a real person. Not sure if the questions are close enough to be duplicates: scifi.stackexchange.com/questions/189968/… – Eike Pierstorff Jul 29 '20 at 10:04

An early story in which a particular individual's personality is reproduced in a machine (described as an 'artificial brain') is "The Infinite Brain" by John Scott Campbell, written under the name John C. Campbell (not to be confused with the more famous science fiction writer and editor John W. Campbell), published in the May 1930 issue of Science Wonder Stories which is available on the internet archive here. I had found this one a couple months ago and added it to the mind uploading in fiction wikipedia page, so I'll just quote my description from there:

The artificial brain is created by an inventor named Anton Des Roubles, who tells the narrator that "I am attempting to construct a mechanism exactly duplicating the mechanical and electrical processes occurring in the human brain and constituting the phenomena known as thought." The narrator later learns that Des Roubles has died, and on visiting his laboratory, finds a machine that can communicate with him via typed messages, and which tells him "I, Anton Des Roubles, am dead—my body is dead—but I still live. I am this machine. These racks of apparatus are my brains, which is thinking even as yours is. Anton Des Roubles is dead but he has built me, his exact mental duplicate, to carry on his life and work." The machine also tells him "He made my brain precisely like his, built three hundred thousand cells for my memory, and filled two hundred thousand of them with his own knowledge. I have his personality; it is my own through a process I will tell you of later. ... I think just as you do. I have a consciousness as have other men." He then explains his discovery that the electrical impulses in the brain create magnetic fields that can be detected by a device he built called a "Telepather", and that "[t]hrough this instrument any one's mental condition can be exactly duplicated." Later, he enlists the narrator's help in constructing a new type of artificial brain that will retain his memories but possess an expanded intellect, though the experiment does not go as planned, as the new intelligence has a radically different personality and soon sets out to conquer the world.


1951: "Izzard and the Membrane", a novella by Walter M. Miller, Jr., first published in Astounding Science Fiction, May 1951, available at the Internet Archive.

The setting is World War III. The hero is an American cyberneticist who is captured and brainwashed by the Soviets and builds them a supercomputer that he calls Izzard or Izzy:

The Izzard was a giant "electronic brain." Its instrument and control panels were erected in a huge subterranean vault, and their length covered three hundred feet of walls. Another vault of equal size was built to house its memory units. A factory behind the Urals devoted itself to the manufacture of special parts according to Scotty's design. Vacuum tubes the size of peas were used for synapses, but they weren't actually tubes at all. There were to be more of them than there were cells in three human brains.

It was not to be a calculator, although it had a math unit too. Its logic and semantic circuits were to solve problems in economics, military strategy, political science, human psychology, sociology, and—cybernetics. The machine would be able to analyze itself, and suggest changes. It could plot the courses of guided missiles from radio signals sent while it was in flight.

Scotty asks Izzy if she is self-aware, and if she can duplicate a human's consciousness. This being a sci-fi story, she is, can, and does. Izzy explains with stfnal gobbledegook:

She replied quickly. "Definition: A transor is a tensor with a complex number of components. Definition: A self-awareness transor is the mathematical function which describes the specific consciousness pattern of one human individual. Related memories: A tensor is a transor with a 'real' number of components. A vector is a tensor with only two or three components. A scalar is a tensor with a single component, i.e., a scalar is a simple number."

[. . . .]

"Yes, human individual's self-awareness transor can be mechanically duplicated."

[. . . .]

Scotty mentally postponed the matter, and as he walked homeward, he tried to piece together the significance of what Izzard had told him.

Her discussion of "self-awareness transors" amounted to just one thing, as he saw it. It amounted to a mathematical definition of something that makes a man himself and not someone else. It was a definition of some elusive human quality, or quantity, which men had once labeled "the soul." And she said that it could be mechanically duplicated.

In the end Scotty has his own self-awareness duplicated in the machine, as well as that of his wife who had died when the Commies nuked Cleveland:

Then he asked her some questions. "Can you cybernetically duplicate more than one human self-awareness transor? Can you duplicate the transor of a deceased person?"

"Answer: Yes, to both questions. Related knowledge from T-memory inventory: A transor is an equation, not a material quantity. It describes the necessary physical neuron-circuit conditions which determine individuality. The equation remains true, even though the individual be dead. Additional knowledge: I have enough circuits to duplicate six consciousness patterns."

Scotty drank in the significance of her words. She was saying in effect that the human soul was as immortal as the mathematical equation that determined its shape. But there seemed to be a slight peculiarity in Izzy's behavior. Where was her emotionless mind securing motivation to make the uncalled-for observations.

Her keyboard began operating again. "Operating note: To duplicate consciousness of deceased, it will be necessary for you to furnish anthropometric and psychic characteristics of the individual. These characteristics will not determine transor, but will only give its general form. Knowing its form, will enable me to sweep my circuit patterns through its mathematical region until the proper transor is reached. At that point, the consciousness will appear among the circuits."

Scotty felt some of the numb ice melt from his soul. "Duplicate Nora MacDonney," he commanded. Then he gave her a personality description of his wife, and it became a glowing picture of tenderness once felt but trampled under the boots of hate. He made it a work of art, painted with the brush of the heart, tinted with Nora's gentleness and wistfulness and inner intensity. And he made a crown of ash blond hair for the pale spirit of his thoughts.

He switched to "answer."

"Related human response: Izzy replied. "I'm no longer your 'best girl.' Good-by, Scotty." Then she set to work.

  • So that's why AI research uses tensor processing units. Fortunately or unfortunately, they haven't developed transor processing units yet. – Tom Anderson Jul 30 '20 at 10:33

In the Frederik Pohl story "The Tunnel under the World" the population of a village destroyed in an accident is recreated as minuscule robots which, as far as the state of their minds is concerned, seem identical to the original people (to the point where they themselves are not aware of the transition). This is from 1955.

As a possible prior example I tentatively nominate the robot from the movie "Metropolis" (1927), but then this is a duplicate/likeness of the character Maria rather than a real "mind upload", so it might not count.


The Annals of the Heechee by Frederik Pohl from 1987 involves a character whose "being" is transferred to a computer system that is interconected much like the internet. At the end of the series of books, it turns out that humans moving to computers saves everyone from what the series termed "The Foe" - energy based beings trying to cause the universe to collapse and reform in a fashion more friendly to energy based life. The Foe had earlier tried to eliminate all phyisical life forms to prevent interference with their plans to reform the universe. The Foe interacts with several of the "computerized humans" and realizes that humans (and other life forms) will all end up converting to energy based life forms long before they could effectively interfere with the plans to regenerate the universe. With all other life firms converted to energy, it would be in everyone's best interests to have the universe converted to be better for energy based life forms.

It is in actually a minor character that causes the realization. The main character (Robinette Broadhead) converts to avoid death. The minor character converted because virtual existence was better than physical existence. The Foe saw that as evidence that everyone would eventually convert to an energy existence.

Buying Time by Joe Haldemann from 1990 involves a character whose "being" is transferred into a computer. At various times, this character inhabits large computers and a thing much like a modern tablet computer.

Those are the two that pop into mind spontaneously.

There may well be earlier ones that I don't know of.

  • If the 1987 one is a match you don't need to include the 1990 one as we are looking for the earliest only. A better idea would be to edit this to explain in more detail how the 1987 story matches and make this into a more complete answer. – TheLethalCarrot Jul 29 '20 at 9:19
  • I had to look up both to get the dates, so I included them both. – JRE Jul 29 '20 at 9:20
  • The Annals of the Heeche is a much later sequel. This happens much earlier in Beyond the Blue Event Horizon (1980). – Spencer Jul 29 '20 at 12:59
