Abstract
Otfrid Foerster was a German neurologist and neurosurgeon who made innovative contributions to neurology and neurosurgery. Foerster performed the first electrocorticographic studies, the hyperventilation test on patient with epilepsy and described the atonic-astatic from of infantile cerebral palsy. He will be remembered best for the operation which bears his name (Foerster's operation) and on creating a cytoarchitectonic map of the human cerebral cortex. His most famous patient was Vladimir Ilyich Lenin (1870-1924).
