Theodore Regensteiner

Theodore Regensteiner (born May 17, 1868 in Munich, Germany to Albert (Abraham) from Pflaumloch and his first wife[1] Fannie, née Heymann.[2] ) He lost his mother age 3 and his stepmother became a determining factor in bringing about his emigration in 1884 (he was age 15) to the USA.[1] His father was the founder of the Albert Regensteiner Mechanische Schuhfabrik - Export - Engros in Pasing near Munich.[3] Theodore R. established himself in Chicago where he joined the printing and publishing business. He is known for inventing the four-color lithographic press 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. He died July 15, 1952 in Chicago, Illinois.[4]

Regensteiner was an executive of the American Colortype Company, which he left after a management dispute in 1906.[5] In June 1907, he founded The Regensteiner Colortype Corporation,[6] which in 1921 became the Regensteiner Corporation.[7]
