Article Summary

Planck was a German theoretical physicist and leader of the German physics community in the first half of the twentieth century. Famous for his introduction of the quantum hypothesis in physics, Planck was also a prolific writer on popular-scientific and philosophical topics. Even more so than his younger contemporary Albert Einstein, Planck was well-known in his day for his defence of a realist conception of science and his explicit criticism of the positivism of Ernst Mach and the Vienna Circle.
