Abstract: We show that in every dimension at least four there exist infinitely many closed manifolds that admit an Einstein metric with negative sectional curvature, but that do not admit any locally symmetric metric (e.g., no hyperbolic or complex-hyperbolic metric). In dimensions at least five, these are the first examples of such manifolds.
