Bertrand Arthur William Russell, 3rd Earl Russell was an influential British logician, philosopher, and mathematician, working mostly in the 20th century. A prolific writer, Bertrand Russell was also a populariser of philosophy and a commentator on a large variety of topics, ranging from very serious issues to the mundane. Continuing a family tradition in political affairs, he was a prominent liberal as well as a socialist and anti-war activist for most of his long life. Millions looked up to Russell as a prophet of the creative and rational life; at the same time, his stances on many topics were extremely controversial.
Born at the height of Britain's economic and political ascendancy, he died of influenza nearly a century later when the British Empire had all but vanished; its power dissipated in two victorious, but debilitating world wars. As one of the world's best-known intellectuals, Russell's voice carried enormous moral authority, even into his early 90s. Among his other political activities, Russell was a vigorous proponent of nuclear disarmament and an outspoken critic of the American war in Vietnam.
In 1950, Russell was made a Nobel Laureate in Literature "in recognition of his varied and significant writings in which he champions humanitarian ideals and freedom of thought".
