DR. JOHN HOLTER

Honorary DSc Sheffield, Honorary CBE, Honorary Member SRHSB
1924-2004

In 1955, after seven years of trying, John and Mary’s first child was born. The birth of Casey Holter turned John Holter’s life upside-down and changed the course of medical history.

Agonisingly, Casey had spina bifida and hydrocephalus. John Holter, then working as a technician in a hydraulics factory, asked surgeons about the details of the procedure. He was surprised that the problem, which seemed to him like a simple hydraulics issue, had not been solved.

He went home, sat in his workshop, and constructed the first version of a valve that very evening. It was a rough-and-ready rubber-tubing and condom prototype, but it worked. Holter had created a usable version within months. So quickly, in fact, that his son was still too weak from the last operation to have it installed.

It was first and successfully installed in another child, and then in March 1956, John Holter’s valve was used in Casey, successfully treating his hydrocephalus.

Sadly, Casey never fully recovered from his brain damage from the previous operations, and he died during an epileptic seizure five years later.

Fittingly, Casey’s legacy is that Holter’s invention, now called the Holter shunt, is still in use today. Holter spent the rest of his life developing valves for medical use and passed away in 2003, having saved the lives of thousands children affected by the same condition as his son.

It is estimated that 15,000 valves based on Holter’s design are installed every year in the United States alone.Extracts from John Holter’s obituary:

Between 1989 and 1993, he donated more than $600,000 to local charities. “I’d rather do it while I’m alive and see it do some good,” he said in 1993, “rather than have an estate and have the lawyers fighting over it.” In 1991, he gave a $100,000 charitable annuity to the United Way of Pinellas County. The gift, in the form of stock, was to transfer to the United Way upon the deaths of Mr. Holter and one other person, whom he declined to name. “I don’t believe in leaving my money to Uncle Sam, and I’m not interested in owning 110-foot yachts,” said Mr. Holter.

John was well-known to SRHSB members and he attended almost every meeting until a few years before his death. He attended the scientific sessions and joined in the discussions.

John donated a sum of money to the Society that has funded an essay prize and a lectureship in memory of his son Casey since 1965, with several subsequent eminent recipients.

SRHSB Executive Committee deeply appreciates Dr. Holter’s generous donation, and considers it to be a key part of the important ‘Gift of Knowledge’ that allows our Society to reach out and interact with all communities concerned with the alleviation of hydrocephalus and spina bifida
