"Bill Foege is one of my heroes. Among his many accomplishments, he was instrumental in ridding the world of smallpox, which is still the only human disease ever eradicated. This book gives you a great view from the front lines of that battle. Bill was a mentor to Melinda and me in the early days of our philanthropy, and he continues to give us great advice today. I also recommend his deeply moving Gates Notes article about fighting river blindness. It’s a fantastic story that gives you real insight into how he thinks about his work."
