HERMANN LUDWIG FERDINAND VON HELMHOLTZ (1821-1894) Beschreibung eines Augen-Speigels zur Untersuchung der Netzhaut im lebenden Auge. A. Förstner'sche Verlagsbuchhandlung 1851 43 [2] pp., plate. 22.5 cm.

One of the scientific giants of his age, Helmholtz made fundamental advances in both physiology and physics, including the establishment of the first law of thermodynamics--that energy can be transformed from one form to another but cannot be created or destroyed. Turning his attention to neurophysiology, Helmholtz became the first to measure the speed of a nerve impulse--a feat Müller had only recently declared to be impossible. Helmholtz's extensive investigations into physiological optics led to his invention of the ophthalmoscope, now one of the most common and useful tools in clinical medicine. The present work constitutes Helmholtz's first description of his invention.
