Grades 1-3. Although her father, the Romantic poet Lord Byron, was bewitched by language, it was numbers that captured Ada Byron Lovelace’s imagination. Raised by her mother, known as the “Princess of Parallelograms” for her passion for geometry, young Ada filled journals with invention ideas, particularly a flying machine. When the measles left Ada blind and paralyzed for years, her mother kept her mind sharp with number problems. And, of course, Ada dreamed of her flying machine. A healthier, teenage Ada was tutored by the accomplished female mathematician Mary Fairfax Somerville, and she was introduced to Charles Babbage and his Difference Machine, a revolutionary calculator. Despite their age difference (she 17 and he 41), Ada was considered an equal, and Babbage asked for her help with his Analytical Engine, a mechanical computer. As she spent months creating an algorithm for the machine, she developed a new profession: computer programming. Soft, delicate yet detailed illustrations evoke Ada’s wonder and accomplishments, with a final spread depicting a spacecraft—a flying machine come true—running a computer language called Ada in her honor. Back matter offers more information on Ada’s life and the world’s first computer program. A beautiful tribute to this female computer pioneer.
