HERMAN HELMHOLTZ1
(1821-1894)
1.Herman Helmholtz is celebrated2
for his-contributions to physiology and theoretical physics. A delicate child, Helmholtz early displayed a passion for
understanding things, but otherwise developed slowly, and had no marked any talent for
mathematics. Although hewished to study physics, he was persuaded by his
father to take up the study of medicine,entering the Medical Institute in Berlin in 1838.
2.His researches into
physiological optics began about 1850 with the discovery of the ophthalmoscope3
(1851), followed by investigations into colour, including the problem of colour-blindness4. He also made fundamental
contribution to the understanding of the structure and mechanism of the human eye.
3. Helmholtz's first, and most celebrated paper in
theoretical physics was his article on the conservation of energy. In this paper he proved
the conservation of total energy of a system of particles, which were interacting
through5 central forces depending only on themasses and separations of the particles. Other
important work in theoretical physics included
the famous paper on vortex motion6 (1858), and the application of
the principle of
least action to electrodynamics problems.
4. Helmholtz was undoubtedly the most versatile7
of nineteenth-century scientists. From 1871 onwards he was perhaps more
famous as a theoretical physicist than as a physiologist.But it seems probable that apart from his work on
the conservation of energy he will ultimately8
be remembered more for his epoch-making researches in physiological optics and acoustics in which his talents as
physiologist, physicist, mathematician and experimentalist were most vividly displayed.
