'Es imposible transmitir la voz humana a través de cables' (1865)
2009-02-16 14:28:00 Corría el año 1854 cuando Antonio Meucci, un ingeniero italiano que había emigrado a Estados Unidos, construyó un teléfono rudimentario para conectar la oficina en la que trabajaba con su dormitorio, en el que reposaba su esposa, aquejada de reumatismo. Como no disponía de los 250 dólares necesarios para patentar el invento, envió los planos y materiales a una empresa para que los estudiaran, pero no les prestaron la menor atención (¡unos genios, oiga usted!). Años después, la información cayó en manos de Alexander Graham Bell, que se sirvió de la misma para desarrollar su teléfono y patentarlo en 1876. Para él fueron el dinero, la fama y la gloria. Tanto es así que no fue hasta el 11 de junio de 2002 cuando el congreso de los Estados Unidos aprobó la resolución 269 que reconocía que el inventor no fue Bell sino Meucci. Como imaginaréis, a mediados de la década de 1860, poca gente, por no decir casi nadie, podía siquiera imaginar que fuera posible hablar con otras personas situada...
