- Edison's Autographic Press and Electric Pen, 1875-1880 - Thomas Edison's electric pen, an ancestor of both the mimeograph and the tattoo needle, was a successful product in the mid-1870s. Users would write normally with the pen, which, instead of a nib, had a needle powered by an electric motor. The needle poked holes into a stencil, which was then used to copy the document. Many businesses found document duplication an attractive possibility.

- Sarah Jordan Boarding House - The Menlo Park complex was an all-male environment; the closest workaday involvement of women -- not forgetting that Edison and several of his personnel were married -- was at the Sarah Jordan boardinghouse. Offering room and board for unmarried employees at the complex, it was operated by Sarah Jordan, a distant relative of Edison's. The house also played host to the experimental lighting system installed throughout Menlo Park in December 1879.
