Описание:

Friedrich Gottlob Koenig (17 April 1774 – 17 January 1833) was a German inventor best known for his high-speed steam-powered printing press, which he built together with watchmaker Andreas Friedrich Bauer, which prints on both sides of the paper at the same time.
He moved to London in 1804 and in 1810 was granted a patent on his press, which produced its first trial run in April 1812. The machine was set up in their workshop, and invitations sent out to potential customers, notably John Walter of The Times.
