| biography:
| Physiologist and physicist, born in Potsdam, EC Germany. He was successively professor of physiology at Königsberg (1849), Bonn (1855), and Heidelberg (1858), and in 1871 became professor of physics in Berlin. He was equally distinguished in physiology, mathematics, and experimental and mathematical physics. His physiological works are principally connected with the eye, the ear, and the nervous system. His work on vision is regarded as fundamental to modern visual science. He invented an ophthalmoscope (1850) independently of Charles Babbage. He is best known for his statement of the law of the conservation of energy, which was more precise and wide-ranging than previous attempts, and well supported with examples of its application. |
