Edison’s electric pen was the first electric motor driven appliance produced and sold in the United States, developed as an offshoot of Edison’s telegraphy research. Edison and Batchelor noticed that as the stylus of their printing telegraph punctured the paper, the chemical solution left a mark underneath. This led them to conceive of using a perforated sheet of paper as a stencil for making multiple copies, and to develop the electric pen as a perforating device. US patent 180,857 for “autographic printing” was issued to Edison on 8 August 1876.
The electric pen was sold as part of a complete duplicating outfit, which included the pen, a cast-iron holder with a wooden insert, a wet-cell battery on a cast-iron stand, and a cast-iron flatbed duplicating press with ink roller. All the cast-iron parts were black japanned, with gold striping or decoration. The hand-held electric pen was powered by the wet-cell battery, which was wired to an electric motor mounted on top of a pen-like shaft. The motor drove a reciprocating needle which, according to the manual, could make 50 punctures per second, or 3,000 per minute. The user was instructed to place the stencil on firm blotting paper on a flat surface, then use the pen to write or draw naturally to form words and designs as a series of minute perforations in the stencil. Later duplicating processes used a wax stencil, but the instruction manuals for Edison’s Electric(al) Pen and Duplicating Press variously call for a stencil of “common writing paper” (in Charles Batchelor’s manual), and “Crane’s Bank Folio” paper (in George Bliss’ later manual). Once the stencil was prepared it was placed in the flatbed duplicating press with a blank sheet of paper below. An inked roller was passed over the stencil, leaving an impression of the image on the paper. Edison boasted that over 5,000 copies could be made from one stencil. The electric pen proved ultimately unsuccessful, as other simpler methods (and eventually the typewriter) succeeded it for cutting stencils. But Edison’s duplicating technology was licensed in 1887 to A.B. Dick, who sold his own system as “Edison’s Mimeograph” with considerable success. The company remained in business as an office products and equipment manufacturer until 2004. The Thomas A. Edison Papers site has a short article on the electric pen, as well as a page of links to key documents about the pen. 2018 update: The Thomas A. Edison Digital Edition, as the online archive is now called, has become more accessible recently, and all material tagged as “Electric pen and mimeograph” may be viewed at this link (1249 items as of June 2018).

To see the electric pen in the context
of other 19th century Edison Electric Pen Registry
Several on-line and print sources have stated that as many as sixty thousand electric pens were produced (a number also quoted by the Smithsonian Institution, although this Smithsonian page cites no source), but it’s likely that this quantity is far too high. The earliest source I have found for this number is an 1889 book by J.B. McClure, “Edison and his Inventions” (right), which describes “...the electric pen, over sixty thousand of which are now in use throughout the country”, but I suspect that this number came from Edison’s publicity machine. The 60,000 number was also reported by Edison's assistant Francis Jehl in his 1937 book “Menlo Park Reminiscences” Vol. 1. However, Jehl would have had no direct knowledge of the production and distribution of the pen during his association with Edison, and writing sixty years after the fact he was almost certainly just quoting the publicized number. The digital edition of the Edison Papers has numerous documents regarding the electric pen, but no list of serial numbers, nor overall information on quantities made. The highest known serial number on a surviving electric pen is 8739; the majority of pens examined to date have a serial number, so it may be significant that nothing higher than this one has yet been found. Further, an analysis of royalty statements found in the Edison Papers accounts for fewer than 4,000 sales between 1876 and 1894; even allowing for unrecorded sales, and in view of the serial number evidence, it’s likely that fewer than 10,000 pens were sold. An 1876 electric pen instruction manual, the cover of which refers to the Philadelphia Centennial Exposition (running from 10 May through 10 November), lists users such as the New York Herald, Mutual Life Ins. Co., New York Central R.R., New York Post Office, and many other large companies, and notes “And 1800 others”. Another manual from that same year amends this to “2500 others”. But on 27 December 1876, Charles Batchelor, who was responsible for the duplicating business, wrote:
These early users were supplied with pens and duplicating presses produced by John Ott, succeeded by Ezra Gilliland, both working under contract out of Edison’s own facilities in New Jersey. Gilliland continued to make the equipment at Menlo Park until manufacturing was transferred to Western Electric in Chicago at the end of 1876. A letter of 10 February 1877 to Edison from George Bliss, who signs himself “General Agent” of the Western Electric company of Chicago (at that time the manufacturer and domestic sales agent for the electric pen), notes:
But further communications from Bliss regarding production problems and late deliveries from Western Electric make it doubtful that this number was ever met, and this is confirmed by royalty payments recorded in Edison’s ledgers. [D7711B] A letter to Thomas Edison dated Dec 6th, 1878, from George Bliss, who is now “General Manager” of Edison’s Electric Pen and Multiplying Press company of Chicago, shows Bliss to be alarmed: “I notice by the papers that you are adapting the Typewriter for the preparation of stencils so as to supercede the use of the electric pen. ... I can scarcely believe this to be possible and shall be glad to have you advise me what the facts are”. [D7822ZCD] These documents indicate that perhaps no more than a thousand duplicating outfits (each including an electric pen) were being sold per year even at the peak of sales activity in the three years following the pen’s invention, and that by the end of 1878 the pen faced serious competition from the newly introduced typewriter. By 1880, there were also many other competing duplicating systems. This production volume information, the analysis of royalty statements mentioned above, and the serial number evidence make it likely that fewer than 10,000 pens were ever sold. Even Western Electric itself, in an February 1881 advertisement, only claimed “10,000 Pens now in Use,” and that number was almost certainly inflated. If you know of an electric pen not on the list below, I’d appreciate receiving its serial number. Pen locations will be listed as “private collection” unless you wish to have your name or business attached to the listing. If the pen is in a public collection, I’d like to be able to list the location, although it’s not essential. Please email me with any information, or feel free to forward my email address to anyone who might be able to help with my research.
