Friedrich Ludwig Gottlob Frege

Gottlob Frege (1848–1925) was a German mathematician, philosopher and logician who contributed greatly to the development of symbolic logic and the launch of analytic philosophy.


Frege's contributions to logic, which began with his 1879 work Begriffsschrift, brought the first major advancement in logic since Aristotle. Frege described a new system of first-order predicate logic that introduced quantification functions and variables for the first time in a symbolic logic.

Frege, who began as a mathematician, wanted to show the logical roots of mathematics. His system replaced Aristotelean syllogistic logic with a wider range of capabilities that allowed the expression of mathematical truths, as well as the symbolization of informal linguistic reason.
