First edition of Helmholtz’s book on his revolutionary invention the ophthalmoscope.

Hermann von Helmholtz (1821–1894) was the first to observe the interior of the human eye, with his invention the “Augen-Spiegel”, that improved the capacity for diagnosing pathological conditions, and became one of the most common and useful tools in clinical medicine.

The eye-mirror, or ophthalmoscope illuminates the otherwise invisible tissues of the eye with a beam of light. Helmholtz calculated that the observer’s line of vision and the direction of the illumination have to be on the same axis, and to solve the problem he used semi-reflective plates placed one on top of the other and positioned at an angle such that the light was reflected into the patient’s eye thus the observer could view the fundus through it. The book contains the calculation and also an illustrative plate with three figures of the ophthalmoscope.

This copy belonged to Sándor Koppi (or Koppy; 1785–1868), a Hungarian physician and author of medical books, and later, according to his inscription in 1880, to Wilhelm Goldzieher.

Goldzieher (1849–1916) studied medicine at the University of Heidelberg where his professors were Otto Heinrich Enoch Becker and Hermann von Helmholtz. He practiced as ophthalmologist, and became a prolific author, also known as the author of the first manual of ophthalmology written in Hungarian (A Szemészet Kézikönyve; 1890).
