British mathematician and philosopher. The son of an earl, Russell was educated at Trinity College, Cambridge. In 1903 Russell published a book on the Principles of Mathematics. Over the years 1910-13 Russell and philosopher Alfred North Whitehead published Principia Mathematica, a three-volume work in which they attempted to establish an axiomatic basis for arithmetic without using the principle of induction. In later life Russell wrote numerous books on philosophy for the popular reader and actively supported world disarmament and social reform.
