Suppose Roald Dahl (September 13, 1916 – November 23, 1990) was a British novelist, short story writer, poet, screenwriter, and wartime fighter pilot. Dahl's works for children include 'James and the Giant Peach', 'Charlie and the Chocolate Factory', and 'Matilda', which have been adapted into popular films.
Can we infer that 'Roald Dahl was primarily known for his medical research.'?
