Overview and metadata sections

Axel Sigurd Burman was a Swedish chemist. His brother Birger F. Burman who resided in U.S., was an engineer. The brothers, in conjunction with businessman Ivor Rennerfelt controlled a patented method for refining alumina from clay. Although the process proved effective, and U.S. patents were secured, the brothers were unable to sell the patent in the U.S. owing to the relatively low cost of bauxite ore, the more common refining method. Upon the death of Birger Burman in 1944, his daughter Svea, Mrs. David Sauer, assumed responsibility for the marketing of the Burman patent rights in the U.S. Despite the assistance of Congressman Lyndon B. Johnson and others, she was unsuccessful in her endeavors.
