Johann Gutenberg and Printing
Luther's 95 Theses and his other works were distributed throughout Germany very quickly. This was the first time printing was used to spread reformatory or revolutionary ideas that were of interest to all classes of society.
Previously, the printing press had only been used for academic texts, for example those dealing with debates or theses; Luther's 95 Theses were actually concieved of in this light.
In 1450, Johannes Gensfleisch the Younger, also called Gutenberg, revolutionized printing. Gutenberg did not invent the printing press, as is often incorrectly assumed; he invented a new printing process.
With this new printing process it was possible to print works quickly and cost efficiently using individual metal letters (single, small metal letters could be placed in rows). These little block letters, which were soon being cast as a series, were reuseable.
