Bertrand Russell

Bertrand Arthur William Russell, 3rd Earl Russell, OM, FRS[7] (18 May 1872 – 2 February 1970) was a British mathematician, philosopher, and public intellectual. He had influence on mathematics, logic, set theory, and various areas of analytic philosophy.[8] He was one of the early 20th century's prominent logicians[8] and a founder of analytic philosophy, along with his predecessor Gottlob Frege, his friend and colleague G. E. Moore, and his student and protégé Ludwig Wittgenstein. Russell with Moore led the British "revolt against idealism".[b] Together with his former teacher A. N. Whitehead, Russell wrote Principia Mathematica, a milestone in the development of classical logic and a major attempt to reduce the whole of mathematics to logic (see Logicism). Russell's article "On Denoting" has been considered a "paradigm of philosophy". https://en.wikipedia.org/wiki/Bertrand_Russell
