The Gundlachs manufactured tools of their own invention. Immediately after the Civil War, Philip M. Gundlach built a new iron foundry powered with Gundlach coal. His son, Joseph, operated the railroad to transport the coal. The P.M. Gundlach Agricultural Mfg. Co. was staffed by his sons: Philip A., Gen. Mgr.; John P., Engr.; Aloys, foreman. They manufactured grain drills, cleaners, hay rakes, wheel hubs and more modern products such as “Packing for Piston Rods and the like”. The family emigrated from Frankfurt, Germany in 1842. The 20th Century Gundlachs were equally inventive. Some were self-educated machinists and tool designers. They respected foundry practices. Gundlach companies include: Gundlach Machinery, founded 1908; T.J. Gundlach Machine Co., founded 1919; Beno J. Gundlach Machine Co., founded 1927; Gundlach Roofing ca. 1900; Specialty Tool ca. 1920.
