Rudolf Carnap (1891–1970) was a prominent philosopher and a key figure in the development of logical positivism and the philosophy of language. He was born in Germany and later became associated with the Vienna Circle, a group of philosophers and scientists who sought to combine ideas from logic and empiricism. Carnap's work focused on the clarification of language and the role of logical analysis in philosophical inquiry.
