How did they get along without faxes and computers?
Someone in one of the reviews asked « how did they get along without faxes and computers? »
Well, in 1963, faxes of a kind had existed for some time...
Around 1900, German physicist Arthur Korn invented the Bildtelegraph, widespread in continental Europe especially, since a widely noticed transmission of a wanted-person photograph from Paris to London in 1908, used until the wider distribution of the radiofax in the 50s. Its main competitors were the Bélinographe by Édouard Belin first, then since the 1930s the Hellschreiber, invented in 1929 by German inventor Rudolf Hell, a pioneer in mechanical image scanning and transmission.
Computers were indeed far and between, but they did exist although I doubt they were used by the French police by then. In 1954, a French insurance company was the first to use a computer in Europe.
