Johann Gutenberg was a German goldsmith and inventor, credited with the inventing of the movable type printing in Europe.Gutenberg was the son of a merchant, and his childhood was spent on a large agricultural estate. From his childhood, he had seen **** and olive presses. By and by, he learnt the art of polishing stones, became a master goldsmith, and also acquired the expertise to create lead moulds used for making trinkets. (Trinket-A small item of jewellery that is cheap or of low quality). Using this knowledge, Gutenberg adapted the existing technology to design his innovation. The olive press became the base model for the printing press and moulds were used for casting the metal types for the letters of the alphabet. By 1448, Gutenberg perfected the system. In 1455, Gutenberg published his 42-lines Bible, commonly known as the Gutenberg Bible. About 180 copies were printed most on paper and some on vellum.
