I want to know the answer to the following question:
Who was the creator of the encyclopedia that The Times was known for selling to America?
All the background I'm provided with is that "During his tenure (1890–1911), The Times became associated with selling the Encyclopædia Britannica using aggressive American marketing methods introduced by Horace Everett Hooper and his advertising executive, Henry Haxton.". Is that enough to answer the question?
