![]() ![]() In the patent for the Automatic Telegraph, the description is as follows: "the transmission is effected by the means of an automatic controller consisting of a pattern strip having predetermined characteristics.which characters are telegraphically reproduced at the receiving station." (Patent 255332) This mimics the punch card system in its representation of information by the use of patterns. Although there is no evidence that shows a connection between the Punch Card system and the Piano roll, there is a similar logic that exists between the linearity of the Piano Roll, and the earliest version of the Punch Card in its roll form.Īnother direct precursor to the Punch Card system was the Automatic Telegraph. Another device that used a similar logic to the Hollerith system was the Piano Roll. This shows a trend of the shift towards mechanical reproduction, and the use of machines to streamline the reproduction process. The lithograph, although not a direct precursor, was a technology that also reproduced visual patterns in the 19th century, with the prospect of graphical reproduction. Charles Babbage, in 1848, envisioned a Punch Card system, but did not have the technological knowledge for the invention. The desired pattern was encoded on cards to be reproduced. These cards were used to control needles to produce the woven product. A technology that won't go away." Wired magazine, Issue 7.03, 1999) In 1804, the card technology was used by Jacques Jacquard as an improvement on the Jacquard loom. (George Dyson, "The little secret that haunts corporate America. Here patterns were coded on a sequence of cards, and were then said patterns were executed on silk. The idea for the punch cards had first been introduced in the 18th century by Jacques de Vaucanson, who invented a card-controlled automatic loom.
