Born Catherine T. Hyland in 1908, she was one of five children of Irish immigrants on [1]

Banker's Life was the basis for John's phenomenal business success in real estate and insurance. Both the foundation and Banker’s Life official press releases state that Catherine was very involved in the success of the businesses and she appears throughout the records of MacArthur’s companies under her maiden name, C.T. Hyland, as corporate secretary or director, sometimes both.[2]

Despite their vast wealth, the MacArthur’s were known for their frugality. In 1963, when he was already one of the wealthiest men in the United States, John MacArthur purchased the Colonnades Hotel in Palm Beach Shores on Singer Island, Florida. Catherine lived with her husband in a modest apartment overlooking the parking lot, while John conducted his business from a back booth in the hotel coffee shop.[3]

When John D. MacArthur died on January 6, 1978, he was worth in excess of $1 billion and was reportedly one of the three richest men in the United States.[1] MacArthur left ninety-two percent of his estate to the John D. and Catherine T. MacArthur Foundation. The foundation’s first board of directors, by John D. MacArthur’s will, included Catherine T. MacArthur, J. Roderick MacArthur (a son from John D. MacArthur’s first marriage), three officers of Bankers Life and Casualty, and radio commentator Paul Harvey.


Catherine T. MacArthur died December 15, 1981 in her Colonnades Hotel apartment.
