Johns-Manville Corporation was established in 1858 when Henry Ward Johns produced the company’s first model of roofing shingles using hot tar and cloth. A decade later, Johns sought out and earned his first patent for an asbestos product, which would become a foundational product for the company. Johns and Manville joined their business ventures when Charles B. Manville and his sons began operating a pipe insulation business that sold Johns’ products. The two officially merged in 1901. The company ran on the qualities of what asbestos could do until its dangers came to fore in the late 1980s.
Collection contains 12 biographical sketches; a book published by Johns-Manville titled Terra Diatomacea by A. B. Cummins; an annual report from 1962; and 8 pamphlets published by the company about their products, advertising, and labor relations.
