Science-fiction writer and professor of biochemistry at Boston University Isaac Asimov, author of the Galactic Empire series (1950-52), the Robot series (1950-85) and the Foundation series (1951-53; 1982-93; 1997-99) among others, lectured in the Chapel. Asimov predicted that the future world would face problems of over-population. This could be prevented, he said, by increasing the status of women, and thus probably decreasing the birth rate.
