Roger Penrose’s professional career began in pure mathematics. Born in Colchester, England, in 1931, he obtained a doctorate in mathematics from St John’s College, Cambridge. His interests turned to the study of space-time structure and he spent a number of years at several American universities before returning to England.

His contributions in theoretical physics reflect his mathematical background for he seems quite at home when moving through multidimensional spaces, projecting infinities, or dissecting hyperspheres. With his imaginative approaches he has established important theories on singularities in space-time which have bearing on the nature of black holes. His insights into the
