The Apgar Score is known the world over: a test given to babies to determine their health moments after they are born. Less well-known is the story of the brilliant, pioneering woman who invented it.Born at the turn of the twentieth century, Virginia "Ginny" Apgar soared above what girls were expected to do--or not do. She wasn't quiet, she wore all sorts of outfits, she played the sports she wanted to--and she pursued the career she chose, graduating near the top of her class at Columbia University and becoming only the second board-certified female anesthesiologist in the United States. The simple five-step test she created--scribbled on the back of a piece of paper in answer to a trainee's question--became the standard and continues to impact countless newborn babies' lives today.Ginny adored science, hated cooking, drove fast, made her own violins, earned a pilot's license, and traveled the world. Here, Carrie Pearson's jaunty storytelling and Nancy Carpenter's playful illustrations capture the energy and independence of a woman who didn't slow down for anything--and changed newborn care forever.
