Did Oxford really "dominate philosophy" in the 20th-century?

So claims a review of three recent books about Oxford philosophy and philosophers.  Even if one limits the claim to Anglophone philosophy, it's not at all obvious this is correct.  Cambridge University, after all, was home to G.E. Moore, Bertrand Russell, Ludwig Wittgenstein (for a time), Frank Ramsey, G.E.M. Anscombe, and (for periods of time) Bernard Williams, Myles Burnyeat, and others.  (The review says, falsely, that analytic philosophy "began at Oxford in the 1920s," Russell and Moore be damned apparently!)  Then there was Harvard with W.V.O. Quine, Hilary Putnam, John Rawls, Nelson Goodman, Robert Nozick, C.I. Lewis, Alfred North Whitehead, T.M. Scanlon, and others.  Just since WWII, Princeton boasted Saul Kripke, David Lewis, Carl Hempel, Gregory Vlastos, Gilbert Harman, and, for periods of time, Donald Davidson, Stuart Hampshire, Alonzo Church, T.M. Scanlon, and Thomas Nagel.  And then UCLA after WWII:  Hans Reichenbach, Rudolf Carnap, Richard Montague, David Kaplan, Tyler Burge, Philippa Foot for a long period of time, and others.
