who was Bartolomeo Cristofori(1655–1731) of Padua?

and what did he invent that we all know of today?

Bartolomeo Cristofori did of course invent the piano, though he may not have recognised this two legged version of it the Boganyi Piano, this piano is the newest and most major change since the instrument was first invented over 300 years ago, earlier this month a new piano design was unveiled in Hungary by pianist Gergely Boganyi, 'it is said that old pianos sound friendly, velvety, while new ones are stronger and more powerful, I was hoping for both', Boganyi has explained, that would make this the ultimate in piano acoustics, while the piano does have a sleek modern look the changes go deeper than that, the design of the piano's exterior itself is meant to maximise the sound being produced through the shape of the two front legs, the third back leg no longer exists, much of the cast iron sides have been removed to open up the movement of the sound, the wild curves of the design are used to get a more powerful and balanced sound,

a new sound board made of 20 carbon composite layers is said to provide a more organic sound, a new type of mechanism that allows the strings to apply minimal pressure on the sound board, the overall design also attempted to remove the temperamental issues that pianos have always faced from variations in temperature, humidity, and other vagaries of life, renowned jazz pianist Gerald Clayton gave the Boganyi a try and said that he felt like he was playing an entirely new kind of instrument, 'the sound almost feels as if you're in a bubble, it's so clear, it's a new sensation', I can hear you now, you want one, and here is the problem, so far there has been no mention of price, but look at around $250,000 and you should be pretty close.
