1900s

One hundred years ago, the gypsum business in North America was fragmented into regional markets. In 1902, 30 independent gypsum rock and plaster manufacturing companies merged to consolidate their resources and form the United States Gypsum Company. The new company combined the operations of 37 mining and calcining plants producing agricultural and construction plaster.
