What happened
Gottlob Frege, born in 1848, published the Begriffsschrift in 1879, constructing the first fully axiomatic system of what would become modern predicate logic and developing an influential distinction between the sense and reference of linguistic expressions. Bertrand Russell, born in 1872, built on this foundation with Alfred North Whitehead in the three-volume Principia Mathematica, published between 1910 and 1913, attempting to derive mathematics from logic, and developed a theory of logical atomism holding that the world consists of a complex of simple logical facts that an ideal language could describe directly. Ludwig Wittgenstein, born in 1889, studied under Russell and published the Tractatus Logico-Philosophicus in German in 1921 and English in 1922, arguing that language works by picturing facts about the world and that many traditional philosophical problems arise from language misused beyond the limits where it can picture anything meaningful.
Why it matters
This sequence of work founded analytic philosophy as a distinct tradition centered on logical and linguistic analysis rather than system-building metaphysics, and Frege's influence on both Russell and Wittgenstein directly shaped a style of philosophy that would dominate English-language academic philosophy through most of the 20th century.
How we know
The Begriffsschrift, Principia Mathematica, and the Tractatus all survive in their original early-20th-century editions and have been continuously studied since publication; the direct lines of influence between the three thinkers, Frege on Russell, both on Wittgenstein, are documented in their own published acknowledgments and surviving correspondence.
