Who invented the famous Coca Cola logo and when did they invent it?

Frank Mason Robinson created the Coca Cola logo in 1885. At the time, he was both John Pemberton's business partner and bookkeeper, and thought the name "Coca cola" provided a great marketing opportunity by the use of two capital C's. The core logo has remained largely unchanged since then, except a brief period in 1890-1891 when it was replaced with what can only be described as a "more swirly" variant.
