Bertrand Arthur William Russell, 3rd Earl Russell OM FRS (18 May 1872 - 2 February 1970) was a British polymath, philosopher, logician, mathematician, historian, writer, social critic, political activist, and Nobel laureate. Throughout his life, Russell considered himself a liberal, a socialist and a pacifist, although he sometimes suggested that his sceptical nature had led him to feel that he had "never been any of these things, in any profound sense". Russell was born in Monmouthshire into one of the most prominent aristocratic families in the United Kingdom. In the early 20th century, Russell led the British "revolt against idealism". He is considered one of the founders of analytic philosophy along with his predecessor Gottlob Frege, colleague G. E. Moore and protégé Ludwig Wittgenstein.
