Gottlob Frege

Gottlob Frege was a German philosopher, logician, and mathematician. He is considered one of the founders of modern logic and made significant contributions to the philosophy of language. Among his most notable works is the development of predicate logic, also known as "Fregean logic".

Extended Aristotelian logic with first-order predicate calculus independently of Charles Sanders Peirce, a crucial precursor in computability theory; also relevant to early work on artificial intelligence, logic programming

Friedrich Ludwig Gottlob Frege was a German philosopher, logician, and mathematician. He was a mathematics professor at the University of Jena, and is understood by many to be the father of analytic philosophy, concentrating on the philosophy of language, logic, and mathematics. Though he was largely ignored during his lifetime, Giuseppe Peano (1858–1932), Bertrand Russell (1872–1970), and, to some extent, Ludwig Wittgenstein (1889–1951) introduced his work to later generations of philosophers. Frege is widely considered to be one of the greatest logicians since Aristotle, and one of the most profound philosophers of mathematics ever.

• Frege is widely considered to be one of the greatest logicians since Aristotle, and one of the most profound philosophers of mathematics ever.
• His contributions include the development of modern logic in the Begriffsschrift and work in the foundations of mathematics.
• His book the Foundations of Arithmetic is the seminal text of the logicist project, and is cited by Michael Dummett as where to pinpoint the linguistic turn.
