Robert M. Hadley

Robert M. Hadley Company, Inc. is a small family owned business founded in 1929 by Robert Hadley in Los Angeles, California. In the beginning, they focused on stamped laminations and fabricated equipment racks. With the popularity of the tabletop radio, Hadley began manufacturing transformers.

Their mechanics designed and built custom winding machines onsite to absorb the numerous orders. Due to the expanding transformer market and sheet metal products, they were able to grow quite rapidly. Hadley developed a reputation for high quality products with a dedication to service. Today, the business continues its success in Ventura, California manufacturing and designing custom transformers and inductors for the aerospace industry.

During WWII, an engineer requested the company’s help in the manufacturing of military grade, hermetically sealed devices. Hadley was able to help the defense contractors meet the country's wartime needs and was acknowledged for their performance as the magnetics supplier with the best quality record nationwide.
