Alexander Graham Bell was an eminent scientist and inventor. A pioneer in the field of telecommunications, Alexander Graham Bell was born in 1847 in Edinburgh, Scotland. At the age of 12, Bell built a homemade device that combined rotating paddles with sets of nail brushes, creating a simple dehusking machine that was put into operation and used steadily for a number of years.
From his early years, Bell showed a sensitive nature and a talent for art, poetry and music that was encouraged by his mother. With no formal training, he mastered the piano and became the family's pianist. Despite being normally quiet and introspective, he revelled in mimicry and "voice tricks" akin to ventriloquism that constantly entertained family guests. Bell was also deeply affected by his mother's gradual deafness, (she began to lose her hearing when he was 12) and learned a manual finger language so he could sit at her side and tap out silently the conversations swirling around the family parlour .He also developed a technique of speaking in clear, modulated tones directly into his mother's forehead wherein she would hear him with reasonable clarity.
Throughout his life, Bell had been interested in the education of deaf people. These interests lead him to invent the microphone and, in 1876, his "electrical speech machine," which we now calls a telephone. News of his invention quickly spread throughout the country, even throughout Europe. By 1878, Bell had set up the first telephone exchange in New Haven, Connecticut. By 1884, long distance connections were made between Boston, Massachusetts and New York City.
Bell is also credited with the invention of the metal detector in 1881. Bell considered the invention of the hydroplane as a very significant achievement. Bell and assistant Frederick W. "Casey" Baldwin began hydrofoil experimentation in the summer of 1908 as |

Bell is also credited with the invention of the metal detector in 1881. Bell considered the invention of the hydroplane as a very significant achievement. Bell and assistant Frederick W. "Casey" Baldwin began hydrofoil experimentation in the summer of 1908 as a possible aid to airplane takeoff from water. In 1913, Dr. Bell hired Walter Pinaud, a Sydney yacht designer and builder as well as the proprietor of Pinaud's Yacht Yard in Westmount, Nova Scotia to work on the pontoons of the HD-4. Pinaud's experience in boat-building enabled him to make useful design changes to the HD-4. Bell's report to the U.S. Navy permitted him to obtain two 350 horsepower (260 kW) engines in July 1919. On 9 September 1919, the HD-4 set a world's marine speed record of 70.86 miles per hour (114.04 km/h). This record stood for ten years.
Bell was a supporter of aerospace engineering research through the Aerial Experiment Association. In 1898, Bell experimented with tetrahedral box kites and wings constructed of multiple compound tetrahedral kites covered in silk. The tetrahedral wings were named Cygnet I, II and III, and were flown both unmanned and manned (Cygnet I crashed during a flight carrying Selfridge) in the period from 1907–1912. Alexander Graham Bell became one of the founding members of the National Geographic Society and he died in 1922.
