The biologist Jacques Loeb (1859-1924) helped to shape the practice of modern biological research through his radical emphasis on reductionist experimentation. This biography traces his career and convincingly argues that Loeb's desire to control organisms, manifested in studies of both reproduction and animal behavior, contributed to a new self-image for biologists. The author places Loeb's experiments and the controversies they generated in their intellectual and institutional contexts, tracing his influence on the development of behaviorism, genetics, and reproductive biology.

Explorers, evolutionists, eugenicists, sexologists, and high school biology teachers--all have contributed to the prominence of the biological sciences in American life. In this book, Philip Pauly weaves their stories together into a fascinating history of biology in America over the last two hundred years.

Beginning with the return of the Lewis and Clark expedition in 1806, botanists and zoologists identified science with national culture, linking their work to continental imperialism and the creation of an industrial republic. Pauly examines this nineteenth-century movement in local scientific communities with national reach: the partnership of Asa Gray and Louis Agassiz at Harvard University, the excitement of work at the Smithsonian Institution and the Geological Survey, and disputes at the Agriculture Department over the continent's future. He then describes the establishment of biology as an academic discipline in the late nineteenth century, and the retreat of life scientists from the problems of American nature. The early twentieth century, however, witnessed a new burst of public-oriented activity among biologists. Here Pauly chronicles such topics as the introduction of biology into high school curricula, the efforts of eugenicists to alter the "breeding" of Americans, and the influence of sexual biology on Americans' most private lives.

Throughout much of American history, Pauly argues, life scientists linked their study of nature with a desire to culture--to use intelligence and craft to improve American plants, animals, and humans. They often disagreed and frequently overreached, but they sought to build a nation whose people would be prosperous, humane, secular, and liberal. Life scientists were significant participants in efforts to realize what Progressive Era oracle Herbert Croly called "the promise of American life." Pauly tells their story in its entirety and explains why now, in a society that is rapidly returning to a complex ethnic mix similar to the one that existed for a hundred years prior to the Cold War, it is important to reconnect with the progressive creators of American secular culture.

The engineering of plants has a long history on this continent. Fields, forests, orchards, and prairies are the result of repeated campaigns by amateurs, tradesmen, and scientists to introduce desirable plants, both American and foreign, while preventing growth of alien riff-raff. These horticulturists coaxed plants along in new environments and, through grafting and hybridizing, created new varieties. Over the last 250 years, their activities transformed the American landscape.

"Horticulture" may bring to mind white-glove garden clubs and genteel lectures about growing better roses. But Philip J. Pauly wants us to think of horticulturalists as pioneer "biotechnologists," hacking their plants to create a landscape that reflects their ambitions and ideals. Those standards have shaped the look of suburban neighborhoods, city parks, and the "native" produce available in our supermarkets.

In telling the histories of Concord grapes and Japanese cherry trees, the problem of the prairie and the war on the Medfly, Pauly hopes to provide a new understanding of not only how horticulture shaped the vegetation around us, but how it influenced our experiences of the native, the naturalized, and the alien--and how better to manage the landscapes around us.
