In 1916, the company began in a backyard workshop in Guelph, Ontario, Canada. The original company, O.S. Hammond and Son, was founded in Guelph in 1917. Between 1919 and 1927, O.S. Hammond and Son began producing tube radio sets, battery chargers, and other related devices. To accommodate the booming broadcast and communications industries, Hammond was the first business in Canada to create a range of 2-post racks and a narrow cabinet in the early 1930s. During the 1950s and 1960s, the rising demand for electrical products presented several chances for new products and diversification. Hammond quickly became a significant provider of transformers, racks, cabinets, and enclosures for the electrical and electronic industries. Hammond has shifted its concentration to the United States and worldwide markets throughout the previous four decades. Hammond completed several key transformer acquisitions and grew to become one of the significant magnetics providers to the North American electrical OEM market. It has also forged strategic agreements with companies in the United States and Europe to expand its extensive range of enclosures and related accessories. The Hammond Transformer Division was spun out into a new company, Hammond Power Solutions, Inc. (HPSI), in 2001. HPSI manufactures custom and catalogue transformers and associated magnetics. Both companies were free to pursue their strategic goals independently after the reorganization. Hammond Manufacturing's primary products include electrical and electronic enclosures, racks and cabinets, power bars, and electronic (low-voltage) transformers.
