    Growing up in New York in the late 1800s was not easy. When she lost her brother and father to typhoid fever, she became determined to pursue her dream of becoming a doctor. In Jo's day, medical schools were closed to women, but times were changing, and Jo was at the forefront.When she graduated in 1898, Dr. Jo still faced prejudice against women in her field. Not many people were willing to be seen by a female doctor, and Dr. Jo's waiting room remained mostly empty. She accepted a job in public health and was sent to Hell's Kitchen, one of New York's poorest neighborhoods where many immigrants lived. There, she was able to treat the most vulnerable patients: babies and children. She realized that the best treatment was to help babies get a stronger start in life.

That is, until Alfred Ely Beach had the idea for a fan-powered train that would travel underground.

She was determined that everyone should have access to the library—not just adults and those who lived in town.

At the age of four, he could ask you when you were born and then calculate the number of seconds you had been alive in his head. But he didn't learn to butter his own bread until he turned twenty. Instead, he traveled around the world, from one mathematician to the next, collaborating on an astonishing number of publications. With a simple, lyrical text and richly layered illustrations, this is a beautiful introduction to the world of math and a fascinating look at the unique character traits that made "Uncle Paul" a great man.
