Leonardo Da Vinci: Giants of Science #1 (Giants of Science (Viking Hardcover)) by Kathleen Krull; 2005. Hardcover. (Ch-NF)

For thirty years, the whole last half of his life, Leonardo da Vinci was obsessed with unlocking the secrets of nature. His notebooks are the mind-boggling evidence of a fifteenth-century scientist standing at the edge of the modern world, basing his ideas on observation and experimentation. Scrupulously researched, juicily anecdotal, this book will change children’s ideas of who Leonardo was and what it means to be a scientist. Award-winning biographer Kathleen Krull will focus on five other "giants of science"— Isaac Newton, Charles Darwin, Marie Curie, Sigmund Freud, and Albert Einstein. Each book presents a compelling portrait of an individual as well as a picture of the world at a particular time and place.
