Alexander Graham Bell — Telephone, Deaf Education

**Alexander Graham Bell** invented the telephone, but that single fact obscures the richer truth: Bell was a speech and hearing scientist whose life's work was human communication, not gadgets. Born in 1847 in Edinburgh, Scotland, into a family obsessed with speech — his father Alexander Melville Bell invented "Visible Speech," a system of phonetic notation for teaching deaf people to speak, and his mother Eliza was profoundly deaf — Bell grew up understanding that communication is the most fundamental human need, and that technology's highest purpose is to extend it.
