John W. Holter (April 1, 1916 – December 22, 2003) was a toolmaker working for the Yale and Town Lock Company Stamford Connecticut. His son Casey Holter was born on November 7, 1955, with a severe form of spina bifida. Shortly after birth he contracted meningitis, which caused his head to expand rapidly. His parents were told that he had developed "water on the brain" or hydrocephalus.[1]

Although he was unable to save his son Casey, his design, the Spitz-Holter valve (also called the Spitz-Holter shunt) continues to help millions around the world since the late 1950s.
