Warren, organized the Pan American Sulphur Company of Mexico in 1947, a business in which Parten was active until its liquidation in 1976. Under his stewardship as chairman of the board, Pan American developed and operated at JÃ¡ltipan, Vera Cruz, Mexico, one of North America's most prolific and profitable sulfur mines. Pan American eventually developed into a major international sulfur company active in European and North American markets.
