What was Johannes Gutenberg's profession?

Johannes Gutenberg was a German inventor and printer born in the later years of the last decade of the fourteenth century. Not content to continue printing using the traditional, incredibly time-consuming method of carving wooden blocks in reverse to use in the printing process, Gutenberg began to experiment with different innovations. Although the printing press had already been invented many centuries earlier in China, Gutenberg replaced wood with metal and large blocks with single, smaller metal pieces, one to a letter: this is called moveable type. He also created his own ink that would adhere more perfectly to metal rather than to wood. In 1452, Gutenberg began to print copies of the Bible, suddenly making the religious text more accessible and affordable and leading to the increased production of books in general as his new technology spread across Europe.
