World War II ...

Never before propaganda had been as important as in the 2nd World War. From now on education was one more field of propaganda: its purpose was to teach how to think, while pure propaganda was supposed to show what to think.
Every nation founded at least one ministry of propaganda - of course without calling it that way. For example the British called it the Ministry of Information (= MOI), the U.S. distinguished between the Office of Strategic Services (= OSS) and the Office of War Information (= OWI), the Germans created a Ministry of Propaganda and Public Enlightenment (= RMVP) and the Japanese called their disinformation and propaganda campaign the "Thought War".
British censorship was so strict that the text of an ordinary propaganda leaflet, that had been dropped from planes several million times, was not given to a journalist who asked for it.

Atrocity stories were no longer used the same way as in the 1st World War. Instead, black propaganda was preferred, especially to separate the Germans from their leaders.
German war propaganda had started long before the war. In the middle of the 1930s Leni Riefenstahl filmed Hitler best propaganda movies. For the most famous one, "Triumph of the Will" (1935), she was the only professional filmier who was allowed to make close-up pictures of her admirer.

Some of the pictures of fear, hatred and intolerance still exist in people's heads. Considering this propaganda did a good job, unfortunately it was the anti-national-socialist propaganda that failed at that time.

Timeline 1900-1970 AD

1913 the wheel cipher gets re-invented as a strip

1917 William Frederick Friedman starts working as a cryptoanalyst at Riverbank Laboratories, which also works for the U.S. Government. Later he creates a school for military cryptoanalysis

- an AT&T-employee, Gilbert S. Vernam, invents a polyalphabetic cipher machine that works with random-keys

1918 the Germans start using the ADFGVX-system, that later gets later by the French Georges Painvin

- Arthur Scherbius patents a ciphering machine and tries to sell it to the German Military, but is rejected

1919 Hugo Alexander Koch invents a rotor cipher machine

1921 the Hebern Electric Code, a company producing electro-mechanical cipher machines, is founded

1923 Arthur Scherbius founds an enterprise to construct and finally sell his Enigma machine for the German Military

late 1920's/30's more and more it is criminals who use cryptology for their purposes (e.g. for smuggling). Elizabeth Smith Friedman deciphers the codes of rum-smugglers during prohibition regularly

1929 Lester S. Hill publishes his book Cryptography in an Algebraic Alphabet, which contains enciphered parts

1933-1945 the Germans make the Enigma machine its cryptographic main-tool, which is broken by the Poles Marian Rejewski, Gordon Welchman and Alan Turing's team at Bletchley Park in England in 1939

1937 the Japanese invent their so called Purple machine with the help of Herbert O. Yardley. The machine works with telephone stepping relays. It is broken by a team of William Frederick Friedman. As the Japanese were unable to break the US codes, they imagined their own codes to be unbreakable as well - and were not careful enough.

1930's the Sigaba machine is invented in the USA, either by W.F. Friedman or his colleague Frank Rowlett

- at the same time the British develop the Typex machine, similar to the German Enigma machine

1943 Colossus, a code breaking computer is put into action at Bletchley Park

1943-1980 the cryptographic Venona Project, done by the NSA, is taking place for a longer period than any other program of that type

1948 Shannon, one of the first modern cryptographers bringing mathematics into cryptography, publishes his book A Communications Theory of Secrecy Systems

1960's the Communications-Electronics Security Group (= CESG) is founded as a section of Government Communications Headquarters (= GCHQ)

late 1960's the IBM Watson Research Lab develops the Lucifer cipher

1969 James Ellis develops a system of separate public-keys and private-keys

Alexander Graham Bell

b., March 3, 1847, Edinburgh

d. Aug. 2, 1922, Beinn Bhreagh, Cape Breton Island, Nova Scotia, Canada

American audiologist and inventor wrongly remembered for having invented the telephone in 1876. Although Bell introduced the first commercial application of the telephone, in fact a German teacher called Reiss invented it.

Time Warner

The largest media and entertainment conglomerate in the world. The corporation resulted from the merger of the publisher Time Inc. and the media conglomerate Warner Communications Inc. in 1989. It acquired the Turner Broadcasting System, Inc. (TBS) in 1996. Time Warner Inc.'s products encompass magazines, hardcover books, comic books, recorded music, motion pictures, and broadcast and cable television programming and distribution. The company's headquarters are in New York City. In January 2000 Time Warner merged with AOL (America Online), which owns several online-services like Compuserve, Netscape and Netcenter in a US$ 243,3 billion deal.
