He later held chairs at Dresden and Vienna, where he took part in founding the Psychological Institute, and after the Nazis briefly detained him in 1938 he emigrated and finally worked in the United States. In linguistics he is known for his organon model of communication and his treatment of deixis. He was the dissertation advisor of Karl Popper.
