Founded in 1902, the United States Gypsum Corporation (USG) emerged from the consolidation of approximately 30 independent gypsum rock and plaster manufacturing companies. This strategic merger aimed to address the fragmented nature of the industry, creating a centralized entity capable of standardizing quality and expanding distribution. By 1917, USG revolutionized the construction industry with the invention of Sheetrock, the world’s first branded drywall. This groundbreaking innovation transformed building construction, offering a faster, more fire-resistant alternative to traditional lath-and-plaster methods. Consequently, USG solidified its position as a leader in the building materials market.

Throughout the 20th century, USG continued to expand its influence through product diversification and technical innovation. However, it also faced significant historical challenges. During the post-World War II housing boom, USG’s product demand surged, leading to the development of acoustical ceiling tiles and specialized joint compounds. Despite these achievements, the company spent decades navigating complex legal and financial hurdles, most notably a massive asbestos-related litigation that ultimately resulted in a Chapter 11 reorganization in 2001. After successfully emerging from bankruptcy and modernizing its operations, USG was acquired by the German-based Knauf Group in 2019 for approximately $7 billion. This acquisition marked the end of USG’s era as an independent American corporation, while ensuring its brands remain essential components of construction sites worldwide.
