The Libbey-Owens-Ford Company (LOF) was a producer of flat glass for the automotive and building products industries both for original equipment manufacturers and for replacement use. The company's headquarters and main factories were located in Toledo, Ohio, with large float glass plants in Rossford, Ohio, Laurinburg, North Carolina, Ottawa, Illinois, Shreveport, Louisiana, and Lathrop, California. The company was formed in 1930 by the merger of Libbey-Owens' sheet-glass operation with the Edward Ford Plate Glass Company, both located in Toledo.
