Manville Corporation was an American company founded in 1858, primarily known for its production of building materials. It gained prominence for its innovative use of asbestos in insulation and other products, which contributed to its growth throughout the 20th century. However, the company faced significant legal and financial challenges due to health concerns related to asbestos exposure. In 1982, Manville Corporation filed for bankruptcy protection, leading to the establishment of a trust fund to compensate victims affected by asbestos-related diseases. Today, the company operates under the name JM and focuses on safer building materials.
