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.
Clearly, since the invention of the sewing machine, many people's way of live has been altered. Elias Howe and Isaac Singer revolutionized clothes and many other products. Although society doesn't think of them as luxuries, a lot of things the sewing machine has provided make a huge difference in daily lives.
