Engelhard: Charles Engelhard began assembling small chemical companies in Newark, NJ, in 1902. In 1905 he named his company the Hanovia Chemical and Manufacturing Company. Engelhard grew to become the largest refiner of platinum, gold, silver, and silver alloys in mill form in the world. In 1963 Engelhard purchased an interest in Minerals & Chemical Phillippe, which was involved in spot trading of precious metals. Explosive growth in the Phillippe sector was disturbing to the slower growing chemical parts of the company, and in 1981 MCP was spun off. The surviving company, Engelhard Corporation, reassumed its role as a major New Jersey-based US chemical company. In 2006 Engelhard was merged into German multinational chemical giant BASF.
