“Depend upon it there comes a time when for every addition of knowledge you forget something that you knew before. It is of the highest importance, therefore, not to have useless facts elbowing out the useful ones.”

British writer and physician

Sir Arthur Conan Doyle was a British writer and physician. He is best known for creating Sherlock Holmes and Dr. Watson, whose stories became landmarks in crime fiction, and for The Lost World, the 1912 novel that helped name a branch of speculative fiction. Beyond those works, he wrote more than 200 stories and articles, along with four volumes of poetry and several stage pieces. He was knighted by King Edward VII in the 1902 Coronation Honours.
