Christian Georg Theodor Ruete
In 1833 obtained his medical doctorate from the University of Göttingen, later serving as an assistant to Karl Gustav Himly (1772–1837). In 1841 he became an associate professor at Göttingen, receiving the title of "full professor" in 1847. Afterwards he was a professor of ophthalmology at the University of Leipzig from 1852 to 1867.
Christian Ruete was a pioneer of German ophthalmology, and made several significant contributions in this field. In 1845 he designed the first ophthalmotrope, a device that serves as a mechanical model of the eye and its muscles, and is used to clarify movements of the eye. In 1857 he constructed an improved version of his earlier prototype. He made modifications to Hermann von Helmholtz's ophthalmoscope by implementing a concave focusing mirror, and thereby introduced "indirect ophthalmoscopy" to allow for a stereoscopic and wider view of the fundus of the eye. Ruete also conducted extensive research of ophthalmic disorders that included strabismus and hypermetropia.
In 1845 Ruete published "Lehrbuch der Ophthalmologie für Aerzte und Studirende", a book that contained the first depiction of a visual migraine aura in European medical literature. In the book, he pictorially explained the phenomenon in three successive stages. With mathematician Johann Benedict Listing (1808–1882), he published a treatise on entoptic phenomena and cataract.
