At least 65 children suffering from water on the brain have had their lives saved by means of the surgical insertion of a Holter brain valve...

Holter now has been provided by Yale & Towne with precision tools in his home workshop in which to devote his full time to producing many more of the lifesaving brain valves...

Holter began a frantic search for a suitable material. He worked evenings and weekends, got only three or four hours' sleep a night. The valve had to be durable.
