1834-REFRIGERDOR (commercial)–Jacob Kins, USA

Although no one knows exactly who invented the refrigerator, be you atribye to Jacob Pérkins because the was that patented it in 1834. Time ago had presented a machine operated by compression of ether, invented by Olivier Evans, who was Jacob Perkins who commissioned by patenting it.

I think that this was the inventions has helped in the history of mankind thus is so as it allows us to retain much more time food and not only in homes is helpful, if not in hospitals and in some industries.
