Frege virtually established the modern discipline of mathematical logic. He developed a strategy of conceptual notation that made it possible for logicians to develop a strict definition of a proof.
Frege is most distinguished, however, for saying that the expressions of language have both a sense and a implication This idea has inspired research in the field of language for over a century.
Gottlob Frege was a German mathematician, logician, and philosopher who worked at the University of Jena. He wrote about the logic of mathematics and language. He was born November 8, 1848, in Wismar, and died July 26, 1925.
