Roald Dahl, author of modern classics like Matilda, The BFG and Charlie and the Chocolate Factory, was born on September 13, 1916 in Wales.
It wasn't until 1961, when Mr. Dahl was 45 years old, that he wrote his first children's book. James and the Giant Peach is still popular today. Who can resist a book with horrid relatives like Aunt Spiker and Aunt Sponge? A cast of over-grown bugs? And a sweetly heroic boy like James?
Practice your math skills with this question: If Mr. Dahl was alive today -- in 2013 -- how old would he be?
