The Diamond Match Company, founded by O. C. Barber as the Barber Match Company, was the largest manufacturer of matches in the United States in the late nineteenth century. Purchased by Jarden in 2003, it has been owned by Newell Brands since Newell Rubbermaid's acquisition of the company in a merger in 2016.
It became a part of the Kreuger concern in 1932, when Ivar Kreuger took control of more than 52% of the shares.
The Diamond Match Company operated plants at Barberton, Ohio; Wilmington, Delaware (now located in the East Brandywine Historic District);Barber, California (later Chico); and Cloquet, Minnesota. In the twenty first century, Diamond remains America's leading producer of matches, producing some twelve billion a year. It also produces plastic cutlery and other wood products.
