||1852: Jan Ernest Matzeliger born ... inventor who is best known for his shoe-lasting machine that revolutionished the shoe industry by replacing the hand work of attaching the sole to the upper of a shoe. He left his homeland of Dutch Guiana and sailed for America at age 19. He settled in Lynn, Massachussetts, by about age 25, where he became a shoe stitching machine operator.
