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 first functional sewing machine was invented by the French tailor, Barthelemy Thimonnier, in 1830. In 1834, Walter Hunt built America's first (somewhat) successful sewing machine. Elias Howe patented the first lockstitch sewing machine in 1846. Isaac Singer invented the up-and-down motion mechanism.
