The principal holdings of the Braga Brothers collection are the records of the Czarnikow-Rionda Company of New York and its subsidiaries and affiliates. From the beginning of the 20th century until the early 1960s, Czarnikow-Rionda was one of North America's largest importers of sugar and molasses. Although it traded in sugar from around the world, its principal source was Cuba. From its offices on Wall Street the company bought and sold ship loads of raw sugar, provided sugar mills with equipment and supplies, and negotiated short term crop loans to Cuba's sugar producers. Czarnikow-Rionda's affiliated companies in Cuba and the United States included cane farms, sugar mills, storage and weighing facilities, a sugar refinery, alcohol distilleries, and cattle ranches. The images below the University of Florida Digital Collections's Cuba Collections show certificates and reports of subsidiaries/affiliate companies in Florida of the Czarnikow-Rionda Company of New York.
