Biografía

Theo Matthew Roald Dahl

Suffered a brain injury at four-months old, when his baby carriage was struck by a taxi. The most serious of his injuries was Hydrocephalus (commonly known as water on the brain). His father, author Roald Dahl, got together with a pair of friends -- a neurosurgeon and an engineer -- and created a device called the Wade-Dahl-Till valve to alleviate cranial pressure. The device allowed Theo and others suffering from Hydrocephalus to recover from their injuries.

Brother of Tessa Dahl, Ophelia Dahl, and Lucy Dahl. His older sister, Olivia Twenty Dahl (b. April 20, 1955 - d. November 17, 1962), died from complications of the measles at the age of seven (when Theo was two).

Son of author Roald Dahl and actress Patricia Neal.

Uncle of model Sophie Dahl.

Daughter Alexa Isabella born on June 26, 2005.
