AKA Gustav. AKA Schröder. Born 1861 in Berlin, moved to U.S. ca. 1881. Worked for Central and then established his own firm, Schroeder & Werner. Lived in California 1891–1899 [Loy, Marin Journal]. One of the most prolific punchcutters of his era. Made type for Inland, Keystone, Marder, Luse & Co., Hawks & Shattuck / Pacific States, and ATF.
Many contemporary sources, such as Loy's biographical sketch [Loy] and even articles by Schroeder's ex-partner N. J. Werner have “Gustav” Schroeder. Saxe and Johnston, in their edition of Loy, choose “Gustave” This is backed up by design patent documents, which say “Gustave F. Schroder”. [MacMillan]
