Since the invention of appropriate means and technologies, communication no longer requires face-to-face meetings.
From writing and reading to using computers, expanding and exhausting one's possibilities to communicate relies more and more on the application of skills we have to learn. With the increasing importance of communication technologies, learning to apply them properly becomes a kind of rite of passage.
A Small World
From the very beginning - the first Sumerian pictographs on clay tablets - to today's state of the art technologies - broadband communication via
Since the invention of the electrical telegraph, but especially with today's growing digital communication networks, every location on earth seems to be close, however distant it may be, and also time no longer remains a significant dimension.
Threatened Cultural Memory
More and more information is transmitted and produced faster and faster, but the shelf life of information becomes more and more fragile. For more than 4500 years Sumerian pictographs written on clay tablets remained intact, but newspapers and books, printed some decades ago, crumble into pieces; film reels, video tapes and cassettes corrode. Digitalization of information is not a cure; on the contrary it even intensifies the danger of destroying cultural heritage. Data increasingly requires specific software and hardware, but to regularly convert all available digitized information is an unexecutable task.
Compared to the longevity of pictographs on clay tablets, digitized information is produced for instant one-time use. The increasing production and processing of information causes a problem hitherto unknown: the loss of our cultural memory.

17th century Cardinal Richelieu invents an encryption-tool called grille, a card with holes for writing messages on paper into the holes of those cards. Afterwards he removes the cards and fills in the blanks, so the message looks like an ordinary letter. The recipient needs to own the same card
- Bishop John Wilkins invents a cryptologic system looking like music notes. In a book he describes several forms of steganographic systems like secrets inks, but also the string cipher. He mentions the so-called Pig Latin, a spoken way of encryption that was already used by the ancient Indians
- the English scientist, magician and astrologer
1605/1623 Sir Francis Bacon (= Francis Tudor = William Shakespeare?) writes several works containing ideas about cryptography. One of his most important advises is to use ciphers in such a way that no-one gets suspicious that the text could be enciphered. For this the steganogram was the best method, very often used in poems. The attempt to decipher Shakespeare's sonnets (in the 20th century) lead to the idea that his works had been written by Francis Bacon originally.
1671 Leibniz invents a calculating machine that uses the binary scale which we still use today, more advanced of course, called the ASCII code
18th century this is the time of the Black Chambers of espionage in Europe, Vienna having one of the most effective ones, called the "Geheime Kabinettskanzlei", headed by Baron Ignaz von Koch. Its task is to read through international diplomatic mail, copy letters and return them to the post-office the same morning. Supposedly about 100 letters are dealt with each day.
1790's Thomas Jefferson and Robert Patterson invent a wheel cipher
1799 the Rosetta Stone is found and makes it possible to decipher the Egyptian Hieroglyphs
1832 or 1838 Sam Morse develops the Morse Code, which actually is no code but an enciphered alphabet of short and long sounds. The first Morse code-message is sent by telegraph in 1844.
1834 the
1844 the invention of the telegraph changes cryptography very much, as codes are absolutely necessary by then
1854 the Playfair cipher is invented by Sir Charles Wheatstone
1859 for the first time a tomographic cipher gets described
1861 Friedrich W. Kasiski does a cryptoanalysis of the Vigenère ciphers, which had been supposed to be uncrackable for ages
1891 Major Etienne Bazeries creates a new version of the wheel cipher, which is rejected by the French Army
1895 the invention of the radio changes cryptography-tasks again and makes them even more important

Supposedly the most famous British atrocity story concerning the Germans during World War I was the "Corpse-Conversion Factory"-rumor; it was said the Germans produced soap out of corpses. A story, which got so well believed that it was repeated for years - without a clear evidence of reality at that time. (

The Independent Institute officially is a "non-politicized, non-partisan, scholarly, public policy research organization" that sponsors studies of social and economic issues. The resulting studies are widely distributed as books and other publications, and are debated in the Institutes conferences and media programs. Areas of research are: Economic issues, social issues, environment and natural resources, industry policy, health and welfare.
