The Invention of the Keyboard

Who invented the music keyboard and when was it invented?  Robert Moog introduced the  modular synthesizer in 1964 which led to modern day electric keyboard.  It can function in the same way as an acoustic piano.  It can sound like many different instruments and so much easier than hauling a piano around.

My daughter has a keyboard, but I'm sure it is not as nice or new as the keyboards you will find here.
