Hermann Wilbrand

Hermann Wilbrand (22 May 1851 – 17 September 1935) was a German ophthalmologist born in Giessen. Wilbrand's father and grandfather were also physicians.

In 1875, he earned his doctorate at the University of Strassburg, and afterwards was an assistant to Ludwig Laqueur (1839-1909) at Strassburg and to Carl Friedrich Richard Förster (1825-1902) at Breslau. Later he moved to Hamburg, where he became head of the department of ophthalmology at Allgemeines Hospital in 1905.

Wilbrand specialized in the field of neuro-ophthalmology and did extensive research involving the pathology and physiology of the eye. He demonstrated that homonymous hemianopsia was caused by lesions in the occipital lobe and optic radiation as well as the optic tract.
