Clyde Hertzman conducted groundbreaking research in early childhood development. Epidemiologist and director of the Human Early Learning Partnership at the University of British Columbia, he scientifically demonstrated how experiences at the earliest stages of life persist and impact well-being over a lifetime. His findings have attracted international attention and resulted in greater emphasis on the early years in provincial and national health strategies. He was also substantially involved in national scientific networks, including the Canadian Institute for Advanced Research.
