In the late 1940s Fisher had become enthralled by the ideas of a radical Austrian economist called Friedrich Hayek.
Hayek believed that the government policies of the post-war period were a form of serfdom.
Companies and individuals should be free to spend what they want.
Fisher wanted to put Hayek's free market philosophy into action, he wanted to become a politician,
but Hayek convinced him his money would be better spent on setting up a new type of organisation called a think-tank.
