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.
The French tailor Barthelemy Thimonnier invented the first sewing machine that could function in 1830. The machine used a single thread and a needle which was hooked. The other tailors burnt his shop and almost killed him as they thought the new invention might bring unemployment.
