c. 1455 CE, February 23
The printing of the Gutenberg Bible, one of the earliest major books printed using movable type, is believed to have been completed in Mainz, Germany on February 23, 1455.
The Gutenberg Bible is named after its creator, Johannes Gutenberg who also invented the wooden printing press, metal types, and oil-based inks used in the new printing process. Historians estimate that Gutenberg printed about 150-180 Bibles in 1455. Only 20 complete copies survive intact and many others exist only as single volumes or fragments.
