The National Association of Mutual Casualty Companies was organized in 1917. This was over twenty years after the creation of the National Association of Mutual Insurance Companies, which was founded in 1895. Attached are excerpts from a 1958 National Association of Mutual Casualty Companies document, which discusses industrial solvents such as benzene. The association acknowledges the assistance of Warren Cook. Mr. Cook was a former director of the division of Industrial Hygiene and Engineering Research for the Zurich-American Insurance Companies.
