When did Jack Genriona invent the keyboard?

Jack Genriona did not invent the keyboard; the invention of the keyboard as we know it today has a more complex history. The first typewriter, which laid the groundwork for modern keyboards, was patented by Christopher Latham Sholes in 1868. The QWERTY layout, commonly used on keyboards, was developed around the same time. If you meant a different context or specific type of keyboard, please clarify!
