“By 1960,” that which later was renamed the American Enterprise Institute “had twelve full-time employees and an annual budget of $230,000,” according to onetime Twentieth Century Fund program officer and historian James A. Smith in his 1991 book The Idea Brokers: Think Tanks and the Rise of the New Policy Elite.

“The money came primarily from large business corporations,” but its president William J. Baroody, Sr., “also tapped the funds of the relatively few foundations that were interested in either conservative causes or economic research, including the Earhart, Falk, Kresge, Pew, and Sloan foundations.”

Sixty years later, where are those five foundations now? Closed, closed, gone left, gone left, and gone left.
