11 febbraio 1847: nasce Thomas Edison #accaddeoggi

Il grande inventore statunitense

Thomas Alva Edison nacque l'11 febbraio 1847 a Milan, nello Stato americano dell'Ohio.

Fin da subito dimostrò curiosità per la scienza e la tecnologia, nonché una forte predisposizione per le invenzioni. Depositò infatti già nel 1868 il suo primo brevetto: uno strumento per la registrazione automatica del voto, che però non ebbe il successo sperato.

Con i guadagni derivati dall'invenzione dello stock ticke, una macchina in grado di ricevere le quotazioni della borsa attraverso la linea telegrafica e stamparle su un foglio di carta, fondò un laboratorio di ricerca a Menlo Park. Qui nel 1877 inventò il fonografo e nel 1879 creò, sulla base del progetto di Joseph Wilson Swan, un modello di lampadina elettrica a incandescenza sufficientemente durevole, che si dimostrò una delle invenzioni più importanti dell'intero XIX secolo.

Thomas Edison morì a West Orange, nel New Jersey, il 18 ottobre 1931.

“Il valore di un'idea sta nel metterla in pratica” Thomas Alva Edison
