Helen was asked to give the annual Dirac Lecture at Cambridge University, sponsored jointly by St John's College and the Department of Applied Mathematics and Theoretical Physics of the University of Cambridge. Her topic: "Antimatter: Dirac's incredible prediction and its consequences." She was the first woman scientist to be selected since the lecture series was begun in 1986. We stayed at St. John's College.
