When MGK® was founded in 1902 by Alexander McLaughlin, its principal business was grinding spices such as cinnamon and pepper, as well as plant leaves, barks, fruits, and flowers used in pharmaceuticals. In 1908, the firm was incorporated with partners George A.N. King and John Gormley. By 1915, MGK was importing a variety of botanicals, including pyrethrum, and wanted to provide its customers with products of consistent and assured quality.
