Etching of Johann Gutenberg (c 1398-1468) regarded as the inventor of movable type, although individual baked clay characters were introduced in China in the 11th century. Gutenberg invented a method of making type of individual letters from molten metal known as typecasting. In 1455 he produced the first large printed book the 'Gutenberg Bible'. He is depicted here holding a stamp with the alphabet in one hand, and a block with the letter 'A' in the other. Part of the Woodcroft Collection 'Gallery of Portraits'.
