MSA was founded in 1914 by John T. Ryan and George H. Deike, two mining engineers who had firsthand knowledge of the terrible human loss that was occurring in underground coal mines. Their knowledge of the mining industry provided the foundation for the development of safety equipment to better protect underground miners. While the range of markets served by MSA has expanded greatly over the years, the founding philosophy of understanding customer safety needs and designing innovative safety equipment solutions remains unchanged.

MSA is headquartered in Pittsburgh, Pennsylvania, with operations employing 5,100 associates throughout the world. A publicly held company, MSA’s stock is traded on the New York Stock Exchange under the symbol MSA.
