Alexander Graham Bell

Bell was a man haunted by the silence of the deaf, a fascination that led him to turn the human voice into a shimmering electrical current. He famously refused to have a telephone in his own study, fearing the persistent intrusion of his own invention upon his thoughts. His curiosity was a runaway train, leading him from the "harmonic telegraph" to experimental hydrofoils and the earliest versions of the metal detector. He didn't just invent a device; he collapsed the distance between human hearts, forever ending the era where a message had to travel at the speed of a horse.
