The sewing machine was invented in 1845. Elias Howe had a dream he was taken prisoner by men with spears ready to do him in. Looking at their spears as they were nearly upon him, he noticed a hole at the spears points. By the next day, this breakthrough led him to develop the missing link in his sewing machine.
