[Karl Eskuchen--a nearly forgotten pioneer in cerebrospinal fluid research]

The author gives a report on the life and the work of Karl Eskuchen (1885-1955), who acted as internal specialist in Munich and Zwickau. With his "puncture of the cerebellomedullary cistern" he gave a remaining contribution to the diagnostics of cerebrospinal space and enlarged the knowledge about physiology and pathology of cerebrospinal fluid.
