who played the leading role in perfecting movable type for printing
Movable type Around 1450, Johannes Gutenberg introduced the metal movable-type printing press in Europe, along with innovations in casting the type based on a matrix and hand mould. The small number of alphabetic characters needed for European languages was an important factor.[3] Gutenberg was the first to create his type pieces from an alloy of lead, tin, and antimonyâ€”and these materials remained standard for 550 years.[4]
