Facing skeptical colleagues, she went to extreme lengths—driving across the country, climbing through windows, and sleeping in her lab—to conduct her work. Her perseverance paved the way for vital scientific discoveries, curing diseases, saving lives, and ultimately earning her a Nobel Prize. (Includes timeline, glossary, and source notes.)
