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 1846, the idea of a sewing machine was nothing new. The first patents for such a machine had been granted in England in 1755, in Austria in 1819, the U.S. in 1826 and France in 1830..Early sewing machines were designed for industrial applications.
