A biography of a 19th-century German scientist renowned for the co-discovery of the second law of thermodynamics and his invention of the ophthalmoscope. The volume relates how von Helmholtz also made contributions to the fields of physiology, philosophy of science and aesthetics.

On January 5, 1845, the Prussian cultural minister received a request by a group of six young men to form a new Physical Society in Berlin. In fields from thermodynamics, mechanics, and electromagnetism to animal electricity, ophthalmology, and psychophysics, members of this small but growing group—which soon included Emil Du Bois-Reymond, Ernst Brücke, Werner Siemens, and Hermann von Helmholtz—established leading positions in what only thirty years later had become a new landscape of natural science. How was this possible? How could a bunch of twenty-somethings succeed in seizing the future? In Aesthetics, Industry, and Science M. Norton Wise answers these questions not simply from a technical perspective of theories and practices but with a broader cultural view of what was happening in Berlin at the time. He emphasizes in particular how rapid industrial development, military modernization, and the neoclassical aesthetics of contemporary art informed the ways in which these young men thought. Wise argues that aesthetic sensibility and material aspiration in this period were intimately linked, and he uses these two themes for a final reappraisal of Helmholtz’s early work. Anyone interested in modern German cultural history, or the history of nineteenth-century German science, will be drawn to this landmark book.

Hermann von Helmholtz was a towering figure of nineteenth-century scientific and intellectual life. Best known for his achievements in physiology and physics, he also contributed to other disciplines such as ophthalmology, psychology, mathematics, chemical thermodynamics, and meteorology. With Helmholtz: A Life in Science, David Cahan has written a definitive biography, one that brings to light the dynamic relationship between Helmholtz’s private life, his professional pursuits, and the larger world in which he lived. ? Utilizing all of Helmholtz’s scientific and philosophical writings, as well as previously unknown letters, this book reveals the forces that drove his life—a passion to unite the sciences, vigilant attention to the sources and methods of knowledge, and a deep appreciation of the ways in which the arts and sciences could benefit each other. By placing the overall structure and development of his scientific work and philosophy within the greater context of nineteenth-century Germany, Helmholtz also serves as cultural biography of the construction of the scientific community: its laboratories, institutes, journals, disciplinary organizations, and national and international meetings. Helmholtz’s life is a shining example of what can happen when the sciences and the humanities become interwoven in the life of one highly motivated, energetic, and gifted person.

Two seemingly contradictory tendencies have accompanied the development of the natural sciences in the past 150 years. On the one hand, the natural sciences have been instrumental in effecting a thoroughgoing transformation of social structures and have made a permanent impact on the conceptual world of human beings. This historical period has, on the other hand, also brought to light the merely hypothetical validity of scientific knowledge. As late as the middle of the 19th century the truth-pathos in the natural sciences was still unbroken. Yet in the succeeding years these claims to certain knowledge underwent a fundamental crisis. For scientists today, of course, the fact that their knowledge can possess only relative validity is a matter of self-evidence. The present analysis investigates the early phase of this fundamental change in the concept of science through an examination of Hermann von Helmholtz's conception of science and his mechanistic interpretation of nature. Helmholtz (1821-1894) was one of the most important natural scientists in Germany. The development of this thought offers an impressive but, until now, relatively little considered report from the field of the experimental sciences chronicling the erosion of certainty.
