Company History

International Sulphur was founded as International Chemicals in 1950 by Robert H. Acock. The first sulphur plant was located at 12 Daly Place in Houston, Texas near the Frasch sulphur mining industry of that time. Ted Brown, the second President of International Sulphur, joined the company in May 1962. Mr. Brown, a civil engineer, oversaw the building of Sulphur Sales, Inc., in 1965 in Middle Point, Ohio. This plant serviced Ohio's large tire and rubber manufacturing industry.

In 1969, a new sulphur plant was built in Mount Pleasant, Texas. This plant location's advantages were the railroad, the new Interstate 30, and an abundance of nearby recovered sulphur. The Houston plant was shut down in 1972 and the Ohio location in 1987. All manufacturing was consolidated at the Mount Pleasant site. In 1990, International Chemical was renamed International Sulfur Inc. to better fit its market niche.

Mr. Acock passed away in December of 1996 and majority ownership of the company was sold to Georgia Gulf Sulfur of Valdosta, Georgia in June of 1997.
