. . Charles Darwin was, above all else, an independent thinker who continues even now to influence the way we look at the natural world. His endless curiosity and passion for detail resulted in a wealth of notebooks, diaries, correspondence, and published writings that Peter Sís transforms into a visual treasure trove. A multilayered journey through Darwin’s world, The Tree of Life begins with his childhood and traces the arc of his life through university and career, following him around the globe on the voyage of the Beagle, and home to a quiet but momentous life devoted to science and family. Sís uses his own singular vision to create a gloriously detailed panorama of a genius’s trajectory through investigating and understanding the mysteries of nature. In pictures executed in fine pen and ink and lush watercolors – cameo portraits, illustrated pages of diary, cutaway views of the Beagle, as well as charts, maps, and a gatefold spread – Peter Sís has shaped a wondrous introduction to Charles Darwin.

    The nation's capital and the largest city in North America is devastated by an apparently incurable disease, cause unknown . . .Jim Murphy describes the illness known as yellow fever and the toll it took on the city's residents, relating the epidemic to the major social and political events of the day and to 18th-century medical beliefs and practices. Drawing on first-hand accounts, Murphy spotlights the heroic role of Philadelphia's free blacks in combating the disease, and the Constitutional crisis that President Washington faced when he was forced to leave the city--and all his papers--while escaping the deadly contagion. The search for the fever's causes and cure, not found for more than a century afterward, provides a suspenseful counterpoint to this riveting true story of a city under siege.
