The Allen-Bradley Company was a pioneering American electronics manufacturer specializing in the design and production of electrical control devices, automation systems, and industrial machinery components. Founded in Milwaukee, Wisconsin in 1903 as the Compression Rheostat Company through the partnership of physician Stanton Allen and brothers Lynde and Harry Bradley, it was renamed Allen-Bradley in 1909. The company grew into one of Wisconsin's largest employers, with production facilities in Milwaukee's Walker's Point neighborhood, and became a leader in industrial automation, producing innovative products like programmable logic controllers (PLCs) that revolutionized manufacturing worldwide. Known for precision engineering, progressive employee welfare policies including profit-sharing and lifetime employment guarantees, and its role in Milwaukee's industrial economy, Allen-Bradley navigated challenges like the Great Depression and World War II through innovation. The Bradley family sold the company to Rockwell International in 1985 for $1.65 billion, ending its era as an independent entity. The sale proceeds significantly funded the Lynde and Harry Bradley Foundation, elevating it to one of the largest U.S. foundations. Today, the Allen-Bradley brand persists under Rockwell Automation, continuing its legacy in industrial automation technologies.
