![]() In this brief quote, Robert Heinlein not only imagines the modern day cell phone, he also foresees the main problem with them. The quote is taken from Lost Legacy, one of the four novellas in this story collection.
This is one of the first mentions of a portable phone usable by ordinary civilians. Also, it specifies that the phone is small enough to actually put in your pocket. Here's another mention of a phone that fits in your pocket from Podkayne of Mars, also by Robert Heinlein.:
"This is Senator Fries. I want the Director... I just called to tell you that I'm coming by to stuff you into one of your own helium tanks. Oh, say about fourteen or a few minutes after. That should give you time to get out of town. Clearing."
He pocketed his phone.
As far as I know, the first reference to a pocket-sized telephone occurs in John Jones's Dollar by Harry Stephen Keeler, published in The Black Cat magazine in 1915; see the pocket wireless phone. See also this reference in Heinlein's 1948 novel Space Cadet - the portable telephone.
Just to put some historical perspective on this one, in 1964 the closest thing to a portable telelphone was a radiotelephone, which was typically the size of a couple of shoeboxes.
Bell System engineers made the first transatlantic radiotelephone call in 1915; it used huge towers and lots of power. The original VHF Squad Radios from WWII were originally designed to be used while riding a horse! The first cellular phones were demonstrated in 1973.
Present day radiotelephones may operate at any frequency where they are licensed to do so, though typically they are used in the various bands between 60 MHz and 900 MHz.
For the WWII generation, a telephone was a fixed object affixed to a wall, or wired into one. It took real effort of the imagination to see a phone you could just put in your pocket. Comment/Join this discussion ( 9 ) | RSS/XML | Blog This | Additional
