 Barthélemy Thimonnier introduced a simple sewing machine in 1841 to produce military uniforms for France's army; shortly afterward, a mob of tailors broke into Thimonnier's shop and threw the machines out of the windows, believing the machines would put them out of work.By the 1850s, Isaac Singer developed the first sewing machines that could operate quickly and accurately and surpass the productivity of a seamstress or tailor sewing by hand.While much clothing was still produced at home by female members of the family, more and more ready-made clothes for the middle classes were being produced with sewing machines.
