Alexander Graham Bell
Alexander Graham Bell - A Famous Scottish-American Scientist
Alexander Graham Bell (1847 - 1922) was the son of a Scottish teacher of speech and elocution who migrated to Washington in 1881, A. G. Berll became a naturalised American in 1882. He is known particularly for his perfection of the telephone, of which he was once thought to be the first inventor. In 1886 the United States Supreme Court acknowledged a prior claim by the Italian Antonio Meucci, who had set up a private instrument in Havana in 1854, while Johann Phillip Reis also made a successful instrument in Germany in 1861. Bell, however, though inspired by reis's telephone, seems to have independently invented an instrument similar to Meucci's. Bell's work was done in Boston USA, where he was a teacher of speech for the deaf, and the first public demonstration of the new means of communication was given by Bell at the Philadelphia Exhibition in 1876. In 1878 he founded the (American) Bell Telephone Company. In 1880 he invented the photophone, which transmitted the first wireless telephone message, and in 1887 the graphophone, one of the earliest gramophones.
