The Havemeyer Sugar Refining Company was a prominent sugar refining business in the United States during the late 19th and early 20th centuries. Founded by the Havemeyer family, the company played a significant role in the sugar industry, particularly in the refining of raw sugar into granulated sugar for consumer use. The company was known for its innovative techniques and large-scale operations, which contributed to the growth of the sugar market. It eventually became part of the larger American Sugar Refining Company, which consolidated many sugar refineries and dominated the industry during that era.
