Bertrand Russell

One of the key philosophers of the earlier 20th C. If Russell was Whitehead’s protégé (they collaborated for six years), so Wittgenstein, arriving as Russell’s PhD student and rapidly identified by him as a genius, was his. Russell met Moore at Cambridge, had a pivotal meeting with Peano in Paris, pointed out a flaw to the thunderstruck Frege, and named his son after his friend Conrad. He planned some lectures with Lawrence, was a friendly critic to Dewey, and was helped out by Santayana. Shaw, the Webbs, Keynes and Woolf were among his many friends, Quine and Carnap among his many correspondents.
