Incorporated in 1970 in IL - Founded by the late John D. and Catherine T. MacArthur. A midwestern businessman and real estate magnate, Mr. MacArthur was one of the country's wealthiest men. He built a vast fortune, primarily through ownership and development of Bankers Life and Casualty Co. of Chicago, the largest health and casualty underwriter in the nation, as well as other businesses including considerable property in Florida and New York. His wife, Catherine T. MacArthur, a board member of both Bankers Life and Casualty and the foundation, died in 1981.
