The Burger Steel Company of Belgium was one of the first non-Mexican companies to be financed by Kramer Associates. In 1891, K. A. President Diego Cortez y Catalán began the company's international operations, financing Burger Steel, as well as railroads in Manchuria and Argentina and a copper mine in the Congo. Although Sobel does not say so, Burger Steel was presumably made a subsidiary of European Kramer during the Jackson restructuring of 1929 - 1933.
Sobel's source for the Burger Steel Company is Stanley Tulin's The Kramer Associates: The Cortez Years (London, 1970).
