The scientist and philosopher Vogt published a number of notable works on zoology, geology and physiology. All his life he was engaged in politics, in the German Frankfurt Parliament of 1848-49 and during his emigration in Switzerland. Karl Marx scathingly replied to his attacks in his book "Herr Vogt" (1860). A proponent of scientific materialism and atheism, Vogt was also an early adherent to the theory of evolution, and Darwin mentions him in his introduction to "The Descent of Man".
