Who was Alexander Graham Bell?
Alexander Graham Bell was an inventor, scientist, and teacher who is best remembered for inventing the telephone. He was born on March 3, 1847, in Scotland, and he and his family moved to England in 1865 and Canada in 1870. A year later Bell moved to the United States, where he taught speech to deaf students and where he also invented and improved a number of electrical technologies. He became a U.S. citizen in 1882 while remaining a British subject; he later moved to Canada and lived there until his death on August 2, 1922.What did Alexander Graham Bell invent?
Although Alexander Graham Bell is best remembered as the inventor of the telephone, he invented other devices too. Bell developed several sonic technologies, including the photophone (1880) and the Graphophone (1886). He also developed medical technology. After the shooting of U.S. Pres. James A. Garfield in July 1881, Bell teamed up with professor Simon Newcomb of the U.S. Nautical Almanac Office to develop an electrical bullet probe. The pair demonstrated the probe in the autumn of 1881. Bell later shifted his attention to aerial technology. He founded the Aerial Experiment Association in 1907.How did Alexander Graham Bell’s telephone work?
The first telephone had two parts: a transmitter and a receiver. The transmitter comprised three parts—a drumlike device (a cylinder with a covered end), a needle, and a battery. The covered end of the drumlike device was attached to the needle. The needle was connected by wire to the battery, and the battery was connected by wire to a receiver. When Bell spoke into the open end of the drumlike device, his voice made the paper and needle vibrate. The vibrations were then converted into an electric current which traveled along the wire to the receiver.BBC - History - Alexander Graham Bell
