Johannes Gensfleisch zur Laden zum Gutenberg was a German inventor and craftsman who invented the movable-type printing press. Though movable type was already in use in East Asia, Gutenberg's invention of the printing press enabled a much faster rate of printing. The printing press later spread across the world, and led to an information revolution and the unprecedented mass-spread of literature throughout Europe. It had a profound impact on the development of the Renaissance, Reformation, and humanist movements.

An invention is a unique or novel device, method, composition, idea or process. An invention may be an improvement upon a machine, product, or process for increasing efficiency or lowering cost. It may also be an entirely new concept. If an idea is unique enough either as a stand-alone invention or as a significant improvement over the work of others, it can be patented. A patent, if granted, gives the inventor a proprietary interest in the patent over a specific period of time, which can be licensed for financial gain.
