Columbus has been home to many manufacturing companies, including Noblitt-Sparks Industries (which built radios under the Arvin brand in the 1930s) and Arvin Industries, now Meritor, Inc. After merging with Meritor Automotive on July 10, 2000, the headquarters of the newly created ArvinMeritor Industries was established in Troy, Michigan, the home of parent company, Rockwell International. It was announced in February 2011 that the company name would revert to Meritor, Inc. Cummins, Inc. is by far the region's largest employer, and the Infotech Park accounts for a sizable number of research jobs in Columbus proper. Just south of Columbus are the North American headquarters of Toyota Material Handling, U.S.A., Inc., the world's largest material handling (forklift) manufacturer. Other notable industries include architecture, a discipline for which Columbus is famous worldwide. The late J. Irwin Miller (then president and chairman of Cummins Engine Company) launched the Cummins Foundation, a charitable program that helps subsidize a large number of architectural projects throughout the city by up-and-coming engineers and architects.
