  Moore's Fellowship ended in 1904; after a spell away from Cambridge, Moore returned there in 1911 to a lectureship in the University and he then lived there for the rest of his life (apart from an extended visit to the U.S.A. in 1940-44). In 1921 he became editor of Mind, the leading British philosophical journal, and in 1925 he became a Professor at Cambridge. These two appointments confirmed his position as the most highly respected British philosopher of the time, and with Wittgenstein back in Cambridge after 1929, Cambridge became the most important centre of philosophy in the world. Moore retired as Professor in 1939 (to be succeeded by Wittgenstein) and as editor of Mind in 1944; these retirements marked not only the end of his pre-eminence, but also of the golden age of Cambridge philosophy.
