Theodore Regensteiner (born 1868, Hamburg, Germany; died July 15, 1952, Chicago, Illinois) migrated to the USA in 1884. He established himself in Chicago where he joined the printing and publishing business. He is known for inventing the four-color lithographic press [1] in 1894 when he requested an extra black plate in addition to the three traditional primaries for the printing of the Christmas issue of Century Magazine.
