Heinrich Lissauer (12 September 1861 - 21 September 1891) was a German neurologist born in Neidenburg (today Nidzica, Poland). He was the son of archaeologist Abraham Lissauer (1832–1908).
He studied at the Universities of Heidelberg, Berlin and Leipzig. He was a neurologist at the psychiatric hospital in Breslau, and was a one-time assistant to Carl Wernicke.
In 1885 he provided a description of the dorso-lateral tract, a bundle of fibers between the apex of the posterior horn and the surface of the spinal marrow, that was to become known as "Lissauer's tract".[1] Another eponymous term associated with Lissauer is "Lissauer's paralysis", a condition that is an apoplectic type of general paresis.
Among his written works was an influential treatise on visual agnosia, being referred to as Seelenblindheit in 19th-century German medicine, a term that roughly translates to "mind blindness". Lissauer died in Hallstatt, Austria on 21 September 1891 at the age of 30.
