In 1840 Thomas Davenport, inventor of the first American DC electric motor, published The Electro-Magnet, and Mechanics Intelligencer  "printed on a press propelled by electro-magnetism" in New York City. This newspaper, published for a short time, was the first newspaper powered by a press powered by electricity. The power for his electric motor he used for the press came from a battery of amalgamated zinc and sheets of platinized silver.[8]

"Davenport was the sole editor of The Electro-Magnet, and Mechanics Intelligencer.[14] The paper was eleven inches by fourteen inches in size and had eight pages with four columns to a page.... The first issue was put out January 18. It had on the front page an article talking about how the power of electro-magnetism and his new invention of the electromagnetic motor could be used for the benefit of people by saving labor.[14][16]

"Davenport wrote in his newspaper on the second issue put out on January 25 on various subjects besides electrical or magnetic related subjects. "No. 2, Vol. 1" looked physically very much like the first issue with the same number of pages and columns. The first page had an article on "The Origin of Galvanism", "The Vision of Columbus", and "The Fancy Dress Ball."[17] He knew there were many skeptics of his new electric motor invention and responded to their concerns in this issue.[14][15]

"Davenport used this application of an electric printing press for demonstration purposes to show an example of what could be done with his new electric motor invention. Many business people submitted possible uses for his new device and he decided that printing a newspaper would be the most effective way of showing what could be done with his invention. In the newspaper he asked for investors to help him financially develop ideas he had for electric motor applications.[14] In spite of his plea for investors in his journal Davenport ultimately did not turn a profit from his motor invention, mainly because the batteries needed to operate it were too expensive." He discontinued the newspaper after publishing it for less than one month.

When I wrote this entry in January 2021 I was unable to find any digitized issue of this very short-lived newspaper.
