4000 - 1000 B.C. 4th millennium B.C. In Sumer Writing and calculating came into being at about the same time. The first pictographs carved into clay tablets were used for administrative purposes. As an instrument for the administrative bodies of early empires, which began to rely on the collection, storage, processing and transmission of data, the skill of writing was restricted to only very few. Being more or less separated tasks, writing and calculating converge in today's computers. Letters are invented so that we might be able to converse even with the absent, says Saint Augustine. The invention of writing made it possible to transmit and store information. No longer the ear predominates; face-to-face communication becomes more and more obsolete for administration and bureaucracy. Standardization and centralization become the constituents of high culture and vast empires as Sumer and China. 3200 B.C. In Sumer the seal is invented. About 3000 B.C. In Egypt papyrus scrolls and About 1350 B.C. In Assyria the cuneiform script is invented. 1200 B.C. According to Aeschylus, the conquest of the town of Troy was transmitted via torch signals. About 1100 B.C. Egyptians use homing pigeons to deliver military information. |

More and more, faster and faster, but... 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.

Chappe's fixed optical network Claude Chappe built a fixed optical network between Paris and Lille. Covering a distance of about 240kms, it consisted of fifteen towers with semaphores. Because this communication system was destined to practical military use, the transmitted messages were encoded. The messages were kept such secretly, even those who transmit them from tower to tower did not capture their meaning, they just transmitted codes they did not understand. Depending on weather conditions, messages could be sent at a speed of 2880 kms/hr at best. Forerunners of Chappe's optical network are the For more information on early communication networks see |

First typewriter patent, 1713 In 1714 Henry Mill got granted a patent for his idea of an "artificial machine or method" for forgery-proof writing, but not before 1808 the first typewriter proven to have worked, was built by Pellegrino Turri for his visually impaired friend, the Countess Carolina Fantoni da Fivizzono. In 1873 commercial production of typewriters began. For a brief history of typewriters see Richard Polt, The Classic Typewriter Page, |
