Spielmeyer–Vogt disease

Spielmeyer, Walter (1879–1935), German neurologist. Spielmeyer is known for his descriptions of a method of microscopic examination of myelin sheaths of the nervous system (1911) and of a fatal form of lipofuscinosis (1908).

Vogt, Heinrich (1875–1957), German neurologist. After psychiatric posts at the universities of Göttingen and Frankfurt, Vogt became director of a neurological sanatorium at Wiesbaden. Following a major change in his area of interest in the 1920s, he commenced a practice in medical hydrology at a health spa and later founded an institute for research in balneology at Breslau (now Wrocław, Poland). He published his own description of what is now known as Batten disease in 1905.
