1713
In 1714 Henry Mill got granted a patent for his idea of an "artificial machine or method" for forgery-proof writing. Still it was not before 1808 that the first typewriter proven to have worked was built by Pellegrino Turri for his visually impaired friend, the Countess Carolina Fantoni da Fivizzono. The commercial production of typewriters began in 1873.

1727
Searching for the Balduinist fluorescenting phosphor (Balduinischer Leuchtphosphor), an artificial fluorescent, Johann Heinrich Schulze realized the first photocopies, but did not put them into practical use.
The first optical photocopier was not patented before 1843, when William Henry Fox Talbot got granted a patent for his magnifying apparatus.
In 1847 Frederick Collier Bakewell developed a procedure for telecopying, a forerunner of the fax machine. Yet it was not before 1902 that images could be transmitted. Almost 200 years after Schulze's discovery, for the first time photo telegraphy was offered as a telecommunication service in Germany in 1922.
1794
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 the communication system was designed for practical military use, the transmitted messages were encoded. The messages were kept such a secret that even those who transmit them from tower to tower did not capture their meaning; they 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

The firm began in Germany in 1835, when Carl Bertelsmann founded a religious print shop and publishing establishment in the Westphalian town of Gütersloh. The house remained family-owned and grew steadily for the next century, gradually adding literature, popular fiction, and theology to its title list. Bertelsmann was shut down by the Nazis in 1943, and its physical plant was virtually destroyed by Allied bombing in 1945. The quick growth of the Bertelsmann empire after World War II was fueled by the establishment of global networks of book clubs (from 1950) and music circles (1958). By 1998 Bertelsmann AG comprised more than 300 companies concentrated on various aspects of media. During fiscal year 1997-98, Bertelsmann earned more than US$15 billion in revenue and employed 58.000 people, of whom 24.000 worked in Germany.
