In the 1970s multimillionaire Howard Ahmanson became a Calvinist and joined Rushdoony's Christian Reconstructionist movement. Ahmanson served as a board member of Rushdoony's Chalcedon Foundation for approximately 15 years before resigning in 1996. Ahmanson said he had left the Chalcedon board and "does not embrace all of Rushdoony's teachings." "Time" magazine covered the Ahmansons in their 2005 profiles of the 25 Most Influential Evangelicals in America, classifying them as "the financiers." Former American oil billionaire Nelson Bunker Hunt also made heavy contributions to the Chalcedon Foundation.
