Jan Matzeliger, American Inventor

Jan Ernst Matzeliger (September 15, 1852 - August 24, 1889) was an African-American inventor in the shoe industry. In the early days of shoe making, shoes were made mainly by hand. Since the greatest difficulty in shoe making was the actual assembly of the soles to the upper shoe, it required great skill to tack and sew the two components together. At the time, no machine could attach the upper part of a shoe to the sole. This had to be done manually by a "hand laster"; a skilled one could produce 50 pairs in a 10 hour day. After five years of work, Matzeliger obtained a patent for his invention in 1883. His machine could produce between 150 to 700 pairs of shoes a day, cutting shoe prices across the nation in half. He sacrificed his health working exhausting hours on his invention and not eating over long periods of time, he caught a cold which quickly developed into tuberculosis. He died in 1889, at the age of 36, never seeing the full profit of his invention.

Jan Matzeliger, American Inventor
Descripción:
Traducción automática: Jan Ernst Matzeliger (15 de septiembre de 1852 - 24 de agosto de 1889) fue un inventor afroamericano en la industria del calzado. En los primeros tiempos de la fabricación de calzado, los zapatos se hacían principalmente a mano. Dado que la mayor dificultad en la fabricación de calzado era el ensamblaje real de las suelas con la parte superior del zapato, se requería una gran habilidad para unir y coser los dos componentes. En ese momento, ninguna máquina podía unir la parte superior de un zapato a la suela. Esto tenía que hacerse manualmente con un "máquina de grabado manual"; un experto podía producir 50 pares en una jornada de 10 horas. Después de cinco años de trabajo, Matzeliger obtuvo una patente para su invento en 1883. Su máquina podía producir entre 150 y 700 pares de zapatos al día, lo que redujo a la mitad los precios del calzado en todo el país. Sacrificó su salud trabajando horas extenuantes en su invento y sin comer durante largos períodos de tiempo, cogió un resfriado que rápidamente se convirtió en tuberculosis. Murió en 1889, a la edad de 36 años, sin ver nunca el pleno provecho de su invento.
