It was over 1500 years later in 1790, that the first workable sewing machine was invented and patented by the British inventor Thomas Saint. Earlier, in 1755, Karl Weisenthal, a German inventor, devised the first sewing machine needle, but did not produce a complete machine.
There was no mention of a machine to go with it, and another 34 years were to pass before Englishman Thomas Saint invented what is generally considered to be the first real sewing machine. In 1790 the cabinet maker patented a machine with which an awl made a hole in leather and then allowed a needle to pass through.
