In his book "Thinking the Unthinkable", Richard Cockett sketched Fisher's role in supporting other emerging think-tanks around the world. Cockett wrote, "On the strength of his reputation with the IEA, he was invited in 1975 to become co-director of the Fraser Institute in Vancouver, founded by the Canadian businessman T. Patrick Boyle in 1974. Fisher let the young director of the Fraser Institute, Dr Michael Walker, get on with the intellectual output of the Institute (just as he had given free rein to Seldon and Harris at the IEA) while he himself concentrated on the fund-raising side". Cockett explained that after his success at the Fraser Institute, Fisher went to New York where in 1977 he set up the International Center for Economic Policy Studies (ICEPS), later renamed the Manhattan Institute. "The incorporation documents for the ICEPS were signed by prominent attorney Bill Casey, later Director of the Central Intelligence Agency". Cockett comments that "under the directorship of William Hammett the Manhattan Institute became probably Fisher's greatest success after the IEA".
