1918 - the year in which the Dahl family moved to Radyr, and into Ty Mynydd (Welsh, meaning 'Mountain House'), an imposing Victorian farmhouse (now demolished) that Roald would later describe as "a mighty house with turrets on its roof and with majestic lawns and terraces all around it" (Boy).

3 - Roald's age when his older sister Astri died of appendicitis, aged 7, in February 1920.
He adored her beyond measure, and her sudden death left him literally speechless for days afterwards. He was so overwhelmed with grief that when he himself went down with pneumonia a month or so afterward, he did not much care whether he lived or died. Roald Dahl on his father's grief over Astri's passing, from 'Boy'.
57 - the age at which Roald's father Harald succumbed to pneumonia and died (about a month after Astri's death).
6 - the number of children that Sofie Magdalene Dahl (then aged 35) was left to bring up on her own; Roald, his sisters Alfhild and Else, his step-siblings Ellen and Louis, and Asta, with whom Sofie was pregnant at the time of Harald's death.

1925 - the year that Roald was removed from Llandaff Cathedral School by his mother (see Did You Know? below) and moved to a boarding school, St. Peter's Preparatory School in Weston–super–Mare, aged 9.
After Roald and four accomplices received a severe caning for 'The Great Mouse Plot' (in which they terrorised the village sweetshop owner, Mrs Pratchett, by placing a dead mouse in a jar of gobstoppers), his furious mother Sofie first reprimanded the headmaster and then withdrew Roald from Llandaff the following term.

A blue plaque was erected in 2009 to commemorate the role that the shop played in Dahl's life and autobiography, Boy (Credit: Jvhertum / Eirian Evans, via Wikimedia Commons).
1930 - the year in which Roald, now aged 13, moved on to Repton Public School in the village of Repton, Derbyshire. He joined in the January, a term later than most of the other pupils, and stayed in The Priory on High Street (still a boys' house for the school today).
2 - the number of pet mice that Roald kept at this time, Marmaduke and Montague. He had to leave them at home when he left for Repton.
12 - the typical number of new chocolate bars that the confectioner Cadburys would occasionally send to Roald and his fellow Priory House boys at Repton Public School, for the purposes of sampling and reviewing. The boys would taste the chocolate 'blind' and complete a checklist to give marks for each new product.
17 - the age at which Roald left Repton Public School, in July 1934.
No, thank you. I want to go straight from school to work for a company that will send me to wonderful faraway places like Africa or China. Roald's response to his mother when offered the option of going on to study at either Oxford or Cambridge.
