Who created Morse Code?

The land telegraph was invented by Samuel F. B. Morse, in the 1830s I think. He built this thing that when a button was pushed at one place, it could cause a clacker to go clack at the other end of a wire many miles long. In order to send information over it, he invented a code of clacks for each letter of the alphabet ... which he modestly called Morse's Code. The message sent as the first public demonstration was "What hath god wrought".
