Janet Browne's biography of Charles Darwin is the best I've read thus far. Her style is limpid and concise, and she succeeds wonderfully in taking us back to the intelectual and social atmosphere of 19th century England. Most importantly, she provides a detailed account of the dynamics on both sides of Darwin's family, and at the end we can understand many of the driving forces behind Darwin's success. Browne's book is definitively not hagiographic; rather, it tries to put Darwin in a definite context, making it clear that he benefited from many people around him. I cannot wait for the second part of her biography!
