Eric Hobsbawm and Peter de Francia were both members of the Geneva Club in the mid-1950s. This shortlived club was an opportunity for left-wing artists and intellectuals to meet. Those who attended their gatherings also included J.D. Bernal, John Berger, Paul Hogarth and Derrick Greaves. Another member was J.B.S. Haldane (1892-1964), the biologist and geneticist whose publications included Philisophy and the Sciences (1938).
