Dahl contributed to the field of neurosurgery too!
In 1960, Roald Dahl’s four-month-old son Theo, who was in a pram, was accidentally hit by a taxi driver in New York City. Due to the accident, Theo suffered a condition that increased his brain’s fluid. To help his son recover, Dahl worked with toymaker Stanley Wade, and his son’s neurosurgeon Kenneth Till to develop the Wade-Dahl-Till valve. This not only helped Theo but several children.
