The Foundations Of The Nineteenth Century

Hermann von Helmholtz (1821-1894) was a polymath of dazzling intellectual range and energy. Renowned for his co-discovery of the second law of thermodynamics and his invention of the ophthalmoscope, Helmholtz also made many other contributions to physiology, physical theory, philosophy of science and mathematics, and aesthetic thought. During the late nineteenth century, Helmholtz was revered as a scientist-sage—much like Albert Einstein in this century. David Cahan has assembled an outstanding group of European and North American historians of science and philosophy for this intellectual biography of Helmholtz, the first ever to critically assess both his published and unpublished writings. It represents a significant contribution not only to Helmholtz scholarship but also to the history of nineteenth-century science and philosophy in general.

A biography of an important but largely forgotten nineteenth-century scientist whose work helped lay the foundation of modern neuroscience. Emil du Bois-Reymond is the most important forgotten intellectual of the nineteenth century. In his own time (1818–1896) du Bois-Reymond grew famous in his native Germany and beyond for his groundbreaking research in neuroscience and his provocative addresses on politics and culture. This biography by Gabriel Finkelstein draws on personal papers, published writings, and contemporary responses to tell the story of a major scientific figure. Du Bois-Reymond's discovery of the electrical transmission of nerve signals, his innovations in laboratory instrumentation, and his reductionist methodology all helped lay the foundations of modern neuroscience. In addition to describing the pioneering experiments that earned du Bois-Reymond a seat in the Prussian Academy of Sciences and a professorship at the University of Berlin, Finkelstein recounts du Bois-Reymond's family origins, private life, public service, and lasting influence. Du Bois-Reymond's public lectures made him a celebrity. In talks that touched on science, philosophy, history, and literature, he introduced Darwin to German students (triggering two days of debate in the Prussian parliament); asked, on the eve of the Franco-Prussian War, whether France had forfeited its right to exist; and proclaimed the mystery of consciousness, heralding the age of doubt. The first modern biography of du Bois-Reymond in any language, this book recovers an important chapter in the history of science, the history of ideas, and the history of Germany.

Nineteenth-century French Jewry was a community struggling to meet the challenges of emancipation and modernity. This struggle, with its origins in the founding of the French nation, constitutes the core of modern Jewish identity. With the Revolution of 1789 came the collapse of the social, political, and philosophical foundations of exclusiveness, forcing French society and the Jews to come to terms with the meaning of emancipation. Over time, the enormous challenge that emancipation posed for traditional Jewish beliefs became evident. In the 1830s, a more comprehensive ideology of regeneration emerged through the efforts of younger Jewish scholars and intellectuals. A response to the social and religious implications of emancipation, it was characterized by the demand for the elimination of rituals that violated the French conceptions of civilization and social integration; a drive for greater administrative centralization; and the quest for inter-communal and ethnic unity. In its various elements, regeneration formed a distinct ideology of emancipation that was designed to mediate Jewish interaction with French society and culture. Jay Berkovitz reveals the complexities inherent in the processes of emancipation and modernization, focusing on the efforts of French Jewish leaders to come to terms with the social and religious implications of modernity. All in all, his emphasis on the intellectual history of French Jewry provides a new perspective on a significant chapter of Jewish history.

Putting physics into the historical context of the Industrial Revolution and the European nation-state, Purrington traces the main figures, including Faraday, Maxwell, Kelvin, and Helmholtz, as well as their interactions, experiments, discoveries, and debates. The success of nineteenth-century physics laid the foundation for quantum theory and relativity in the twentieth. Robert D. Purrington is a professor of physics at Tulane University and coauthor of Frame of the Universe.

Héctor Lindo-Fuentes provides the first in-depth economic history of El Salvador during the crucial decades of the nineteenth century. Before independence in 1821, the isolated territory that we now call El Salvador was a subdivision of the Captaincy General of Guatemala and had only 250,000 inhabitants. Both indigo production, the source of wealth for the country's tiny elite and its main link to the outside world, and subsistence agriculture, which engaged the majority of the population, involved the use of agricultural techniques that had not changed for two hundred years. By 1900, however, El Salvador's primary export was coffee, a crop that demanded relatively sophisticated agricultural techniques and the support of an elaborate internal finance and marketing network. The coffee planters came to control the state apparatus, writing laws that secured their access to land, imposing taxes that paid for a transportation network designed to service their plantations, building ports to expedite coffee exports, and establishing a banking system to finance the new crop. Weak Foundations shows how the parallel process of state-building and expansion of the coffee industry resulted in the formation of an oligarchy that was to rule El Salvador during the twentieth century. Historians and economists interested in the "routes to underdevelopment" followed by Latin American and other "Third World" countries will find this analysis thorough and provocative.
