Branch of Science Physicists Nationality German Helmholtz, Hermann von (1821-1894) German physicist who first extended Joule's results to a general principle. He expressed the relationship between mechanics heat light electricity and magnetism by treating them all as manifestations of a single force He presented a mathematical proof for his Law of Conservation of Force in 1847). Helmholtz's use of the word "force" corresponds to what later became known as energy so his law actually amounted to a statement of the Law of conservation of energy Helmholtz sought to synthesize Maxwell's electromagnetic theory of light with the central force theorem. To accomplish this, he formulated an electrodynamic theory of action at a distance in which electric and magnetic forces were propagated instantaneously. He attempted to demonstrate that body heat and muscular action of animals could be produced by the oxidation of foodstuffs.

A pioneer of physiology and physics, he was also deeply concerned with the implications of science for philosophy and culture. From the 1850s to the 1890s, Helmholtz delivered more than two dozen popular lectures, seeking to educate the public and to enlighten the leaders of European society and governments about the potential benefits of science and technology to a developing modern society. David Cahan has selected fifteen of these lectures, which reflect the wide range of topics of crucial importance to Helmholtz and his audiences. Among the subjects discussed are the origins of the planetary system, the relation of natural science to science in general, the aims and progress of the physical sciences, the problems of perception, and academic freedom in German universities. This collection also includes Helmholtz's fascinating lectures on the relation of optics to painting and the physiological causes of harmony in music, which provide insight into the relations between science and aesthetics.

In 1858 he became professor of anatomy and physiology at Bonn, then in 1871, professor of physics at Berlin. His most important work was in mathematical physics and acoustics where his major study of 1863 was interested in musical theory and the perception of sound. In mathematical appendices he advocated the use of Fourier series. He published an important paper on the first law of thermodynamics in 1842. Helmholtz investigated the properties of non-Euclidean space and showed that these could be worked with as easily as the geometry of three dimensions.

Hermann Helmholtz Helmholtz, Hermann Ludwig Ferdinand von One of the 19th century's greatest scientists, Hermann Ludwig Ferdinand von Helmholtz (1821-1894), made important discoveries in physiology, optics, electrodynamics, mathematics, and meteorology. Although he was primarily interested in physics, he entered the Friedrich Wilhelm Medical Institute in Berlin because the state subsidized medical, but not purely scientific, education. Upon his graduation in 1842, he joined a military regiment at Potsdam. In 1858 he became a professor of anatomy and physiology at the University of Bonn. As his scientific interests changed, he became professor of physics at the University of Berlin in 1871 and the first director of the Physico-Technical Institute of Berlin in 1888. Helmholtz rejected the then-prevalent German concept that life processes involve nonphysical vital forces. He and several other associates, particularly Emil duBois-Reymond and Karl Ludwig, formed the so-called 1847, or mechanistic, school of physiology, which attempted to explain physiological phenomena in terms of physics and chemistry. In a series of papers published between 1843 and 1847, Helmholtz applied these principles to animal heat and muscle contraction. This application led to his classic paper, "On the Conservation of Energy" (1847), in which he outlined the philosophical and physical basis of the law of the conservation of energy (enunciated by several other investigators working independently at about the same time).

Even German readers have often to rely on the microform version of Koenigsberger which is part of the Landmark of Science collection. A book reprint will be much more useful. And since there is no biographical account of Helmholtz up until today, Koenigsberger remains the most important source….’ – Dr. Henning Schmidgen, Max Planck Institute for the History of Science, Berlin Hermann Ludwig Ferdinand von Helmholtz (1821–94) had a huge influence on German science during the mid nineteenth century, bringing it to the forefront of world attention. He was a physicist and psychologist who made seminal contributions in both fields. His Treatise on Physiological Optics (reprinted last year by Thoemmes Press) transformed the study of vision by integrating its physical and psychological dimensions. Helmholtz explained the mechanism of ‘accommodation’, invented the ophthalmoscope, and revived the three-colour theory of vision first proposed in 1801 by Thomas Young. He also invented the telestereoscope, produced some novel visual illusions, and argued for the involvement of knowledge in perception. Helmholtz was an inspiration to many others – notably his student Heinrich Hertz, the discoverer of radio waves. Leo Koenigsberger’s three-volume Hermann von Helmholtz (1902–1903) is one of the great scientific biographies of the early twentieth century. Exhaustive and scholarly, it contains a wealth of detail about Helmholtz’s personal and professional life. The books are illustrated with remarkable portraits, and a facsimile of a handwritten letter from Helmholtz to his father is included in an appendix. Koenigsberger’s work remains the standard life of Helmholtz to this day. It has never been fully translated into English, and even in the original German it is scarce. At a time when interest in the life and work of Helmholtz is increasing across the world, Thoemmes Press is pleased to be able to make this vital source more widely available.
