POLAROID CAMERA

  • The Polaroid camera is a camera that develops the photograph while you wait (one-step photography ). It was invented by Edwin Herbeert Land (1909-1991), an American physicist and inventor who also investigated the mechanisms of color perception, developed the first modern light polarizers (which eliminate glare), and other optical devices. Land established the Polaroid Corp. in 1937.

TOILET PAPER

  • Joseph Gayetty invented toilet paper in 1857. His new toilet paper was composed of flat sheets. Before Gayetty's invention, people tore pages out of mail order catalogs - before catalogs were common, leaves were used. Unfortunately, Gayetty's invention failed. Walter Alcock (of Great Britain) later developed toilet paper on a roll ( instead of in flat sheets). Again, the invention failed.
  • In 1867, Thomas, Edward and Clarence Scott (brothers from Philadelphia, Pennsylvania, USA) were successful at marketing toilet paper that consisted of a small roll of perforated paper . They sold their new toilet paper from a push cart - this was the beginning of the Scott Paper Company.
