Arthur Conan Doyle

Sir Arthur Ignatius Conan Doyle (22 May, 1859 – 7 July, 1930) was a British writer. He is most famous as the creator of the character Sherlock Holmes.

I should dearly love that the world should be ever so little better for my presence. Even on this small stage we have our two sides, and something might be done by throwing all one's weight on the scale of breadth, tolerance, charity, temperance, peace, and kindliness to man and beast. We can't all strike very big blows, and even the little ones count for something.
