Why is sir Arthur Conan Doyle an important author?

Yes, I think he should be remembered as one of the greatest writers of all time, and I know he will be remembered for centuries to come. The reason I think this is because he has been since 1930 and apparently you know about him, so you probably heard it from somebody, you learned it in class, or you heard about him from a friend. In other Words, you might recommend this author, the school will teach people about him, or your friend will recommended this author.
