The BFG

The author Roald Dahl is responsible for significant developments in the surgical management of paediatric hydrocephalus and shunt valve technology. This was after his son, Theo Dahl, required a shunt after a traffic accident in 1960. Dahl discovered that existing technology was extremely unreliable and would often fail. So he worked tirelessly to improve upon the design, eventually producing the Wade-Dahl-Till valve.
