A machine imagined as a spiritual breakthrough
John Murray Spear’s project belonged to a nineteenth-century spiritualist movement that treated communication with the dead as more than a matter of private comfort. Spiritualists often believed that departed people could guide the living toward social and technological progress. In Spear’s account, celebrated inventors—including Benjamin Franklin—were among the spirits providing that guidance.
That belief gave the machine a purpose beyond performing a task. Spear presented it as a new source of power, a device meant to help usher in a transformed society. Its construction in the 1850s turned an invisible claim about spirit communication into something followers could gather around and build with their hands.
Why the machine was treated like a birth
The group’s language and rituals made the project resemble the arrival of a new being. A woman’s simulated labor was part of that symbolism: the machine was not merely assembled but, in the followers’ view, brought into the world and given a kind of spiritual life. Copper, zinc, and gears supplied its physical body; the ritual expressed what its builders believed the body needed in order to become more than metal.
This was not an engineering process for installing a soul, nor evidence that spirits had designed a working power source. It shows how spiritualists could interpret technology through their religious ideas. At a time when machinery was rapidly changing everyday life, Spear’s followers imagined that spiritual guidance might direct invention toward human improvement.
The consequence was an idea made visible
The machine’s importance lies less in what it could do mechanically than in what its creation made tangible: a community’s expectation that the dead could participate in the future. The simulated birth gave that expectation a memorable form—one in which a proposed invention was treated not as a tool to be switched on, but as a new life entering the world.
