Roald Dahl is born in Llandaff, near the Welsh capital of Cardiff, on 13th September 1916.
Roald's parents, Harald Dahl and Sofie Magdalene Hesselberg, were both Norwegian and he was named after Norway's famous polar explorer, Roald Amundsen.
At the time of his birth Roald had two older sisters, Astri (born 1912) and Alfhild (born 1914), as well as an older brother and sister from his father’s first marriage, Ellen (born 1903) and Louis (born 1906.)
Roald's father Harald was a shipbroker and his business, Aadnesen and Dahl, was very successful. In Boy, Roald describes a shipbroker as "a person who supplies a ship with everything it needs when it comes into port - fuel and food, ropes and paint, soap and towels, hammers and nails, and thousands of other tiddly little items."
The country that Roald was born into was in the midst of the First World War. In France the Battle of the Somme, one of the largest and bloodiest battles in the conflict, was raging.
Following the birth of Roald Dahl's younger sister Else, the Dahl family move to Ty Mynydd, a large Victorian farmhouse at Radyr, a village just outside Cardiff, Wales. Roald remembered Ty Mynydd in Boy as "a mighty house with turrets on its roof and with majestic lawns and terraces all around it."
In November 1918 the First World War ends in victory for the Allies.
