A very nice piece by Rebecca Bizonet at the Heny Ford Blog; clearing out archives at the Henry Ford Museum, she has encountered a fair number of telegrams, and guess what – abbreviations and shortcuts associated with Twitter, texting, and the like, are nothing new; our predecessors had to use shortcuts too. Not only for Telegrams, which could get pricey if one got wordy, but also because, as Bizonet credits Stephen Fry for pointing out, during the 17th and 18th centuries paper was a precious commodity and therefore a kind of shorthand was used in order to cram as much content onto a single sheet as possible.
