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.
Altering an important element of daily life, the sewing machine was an innovation on a personal yet universal level. The creation process of the sewing machine was the work of several men over a number of years, however, Elias Howe, Jr. is ultimately considered the inventor of the sewing machine.
