by Kathleen Krull
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."
