Johannes Gensfleisch zur Laden zum Gutenberg was a15th century German goldsmith, printer and publisher who introduced modern book printing. His invention of mechanical movable type printing started the Printing Revolution and is widely regarded as the most important event of the modern period. It played a key role in the development of the Renaissance, Reformation and the Scientific Revolution laying the basis for the modern knowledge-based economy and the spread of learning to the masses.
Gutenberg was among the first Europeans to use movable type printing, in around 1439, and the global inventor of the printing press. Among his many contributions to printing are: the invention of a process for mass-producing movable type; the use of oil-based ink; and the use of a wooden printing press similar to the agricultural screw presses of the period. His truly significant invention was the combination of these elements into a practical system which allowed the mass production of printed books and was economically viable for printers and readers alike. Gutenberg's method for making type is considered to have included a type metal alloy and a hand mould for casting type.
The use of movable type was a marked improvement on the handwritten manuscript, which was the existing method of book production in Europe, and upon woodblock printing, and revolutionized European book-making. Gutenberg's printing technology spread rapidly throughout Europe and later the world.
