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.
In 1790 an Englishman named Thomas Saint was granted a patent for a sewing machine design. But there is no proof that Saint, a cabinet maker, ever built his machine. Later when a prototype was built based on his descriptions, it didnât work. So he canât be considered as the one who invented the sewing machine.
