Celebrating 100 Years in 2015

Carus

History

Carus was founded in 1915 by Dr. Edward Hegeler Carus, who first produced permanganate while at the University of Wisconsin. When World War I in Europe threatened supplies of potassium permanganate in the United States, Carus saw an opportunity. Today, Carus' CEO, Inga Carus, represents the third generation of the Carus family to manage the corporation.

During its history, Carus' ongoing reliance on research and development, as well as its emphasis on technical support and customer service, has enabled the company to become the world leader in permanganate, manganese, oxidation, catalyst and blended phosphate technologies.

Today, Carus Group Inc. manufactures a range of products for the municipal and industrial markets with the majority of products used in environmental applications.
