I began my career with the Population Council in 1973, and in 2015 I retired as its president. One of the joys of working at the Council was being surrounded by public health and social science all-stars. Council researchers have changed the way the world thinks about important health and development issues and influenced policies and practice on family planning, the rights and health of girls, and population change. A highlight of my career has been seeing Population Council vice president and distinguished scholar John Bongaarts speak before standing-room-only-audiences in New York, New Delhi, and Addis Ababa. Like a small number of superstars in other professions, John can fill a hall in any of the world’s capital cities.
