In 1932, James Watson Kernohan 1) was the first to use the term myxopapillary in the division of his large series of spinal ependymomas into epithelial, cellular, and myxopapillary types on the basis of cytological architecture.
Kernohan has been recognized as the first neurosurgeon to report an intramedullary schwannoma though Penfield had already described an intramedullary lesion with schwannomas characteristics in 1932 2).
The Mount Sinai Hospital was founded in 1852 under the name “The Jews' Hospital.” Neurosurgery at Mount Sinai Hospital can be traced to the work of Dr. Charles Albert Elsberg. In 1932, the Department of Neurosurgery was created under the direction of Dr. Ira Cohen. The history of neurosurgery at the Mount Sinai Hospital is recounted by Oppenheim 3).
In 1929, N.N. Burdenko and a neurologist V.V. Kramer founded the first neurosurgical clinic in Moscow, which was reorganized to the Institute of Neurosurgery in 1932. The Institute has come a long way through military and peaceful years, overcoming all sorts of obstacles. It has constantly developed, built, and modernized, and now this is the National Medical Research Center of Neurosurgery 4).
