About Walter Dandy
Walter Edward Dandy (April 6, 1886 – April 19, 1946) was an American neurosurgeon and scientist. He is considered one of the founding fathers of neurosurgery, along with Victor Horsley and Harvey Cushing. Dandy is credited with numerous neurosurgical discoveries and innovations, including the description of the circulation of cerebrospinal fluid in the brain, surgical treatment of hydrocephalus, the invention of air ventriculography and pneumoencephalography, the description of brain endoscopy, the establishment of the first intensive care unit, and the first clipping of an intracranial aneurysm, which marked the birth of cerebrovascular neurosurgery. During his 40-year medical career, Dandy published five books and more than 160 peer-reviewed articles while conducting a full-time, ground-breaking neurosurgical practice in which he performed during his peak years about 1000 operations per year. He was recognized at the time as a remarkably fast and particularly dexterous surgeon. Dandy was associated with the Johns Hopkins University School of Medicine and the Johns Hopkins Hospital his entire medical career. The importance of his numerous contributions to neurosurgery in particular and to medicine in general has increased as the field of neurosurgery has evolved. Dandy's first scientific contribution was the detailed anatomical description of a 2 mm human embryo in Franklin P. This congenital anomaly became known as the Dandy-Walker cyst.
