The shoemaker (late 19th century). Jan Matzeliger, born in 1852, immigrated to the US "at age 18 and went to work in a shoe factory in Philadelphia. Shoes then were hand made, a slow tedious process. Jan Matzeliger helped revolutionize the shoe industry by developing a shoe lasting machine that would attach the sole to the shoe in one minute."
