 The annexation of Austria in 1938 became the catalyst which prompted Popper to refocus his writings on social and political philosophy. He published The Open Society and Its Enemies, his critique of totalitarianism, in 1945. In 1946 he moved to England to teach at the London School of Economics, and became professor of logic and scientific method at the University of London in 1949. From this point on his reputation and stature as a philosopher of science and social thinker grew, and he continued to write prolifically—a number of his works, particularly The Logic of Scientific Discovery (1959), are now widely seen as pioneering classics in the field. However, he combined a combative personality with a zeal for self-aggrandisement that did little to endear him to professional colleagues. He was ill-at-ease in the philosophical milieu of post-war Britain which was, as he saw it, fixated with trivial linguistic concerns dictated by Wittgenstein, whom he considered his nemesis. Popper’s commitment to the primacy of rational criticism was counterpointed by hostility towards anything that amounted to less than total acceptance of his own thought, and in Britain—as had been the case in Vienna—he increasingly became an isolated figure, though his ideas continued to inspire admiration.
