Graham bell

Alexander Graham Bell, best known for his invention of the telephone, revolutionized communication as we know it. His interest in sound technology was deep-rooted and personal, as both his wife and mother were deaf. Ultimately, the talented scientist held more than 18 patents for his inventions and work in communications. Young Alexander was an intellectually curious child who studied piano and began inventing things at an early age. Both of his brothers passed away from tuberculosis by the time Bell was in his early twenties. When he was just 12, the young Alexander invented a device with rotating paddles and nail brushes that could quickly remove husks from wheat grain to help improve a farming process. At age 16, Bell began studying the mechanics of speech. In , Bell, along with his family, moved to Canada. The following year, he settled in the United States. While in the U.

Bell's father , grandfather, and brother had all been associated with work on elocution and speech and both his mother and wife were deaf, profoundly influencing Bell's life's work. Many other inventions marked Bell's later life, including groundbreaking work in optical telecommunications , hydrofoils , and aeronautics. Although Bell was not one of the 33 founders [10] of the National Geographic Society , he had a strong influence on the magazine while serving as the second president from January 7, , until Beyond his scientific work, Bell was an advocate of compulsory sterilization and served as chairman or president of several eugenics organizations. Alexander Bell was born in Edinburgh , Scotland, on March 3, He had two brothers: Melville James Bell — and Edward Charles Bell — , both of whom would die of tuberculosis. As a child, young Bell displayed a curiosity about his world; he gathered botanical specimens and ran experiments at an early age. His best friend was Ben Herdman, a neighbour whose family operated a flour mill. 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 at the mill 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.

Alexander Graham Bell was the first to secure a patent for the telephone, but only just. And it almost cost him his marriage At the age of eleven he chose to add the middle name Graham, which stuck for the rest of his life. Both his father and grandfather were well-known teachers of elocution and speech training; his father in Edinburgh, his grandfather in London. This type of model was used to teach anatomy students the complexities of human vocal physiognomy. Encouraged by his father, young Bell attempted to make working models of ears and vocal cords, aiming to create a mechanical speech device. He attended classes in anatomy and physiology in London for several years, building his understanding of how speech and hearing worked. These early experiments in speech creation, along with his knowledge of anatomy, informed his own experiments on transmitting speech, which he began in earnest from Through study and experimentation, Bell hypothesised that if sound waves could be converted into a fluctuating electric current, then that current could then be reconverted into sound waves identical to the original at the other end of the circuit. On 10 March , the first intelligible telephone communication was made.

When he was just 12, the young Alexander invented a device with rotating paddles and nail brushes that could quickly remove husks from wheat grain to help improve a farming process.

At age 16, Bell began studying the mechanics of speech. In , Bell, along with his family, moved to Canada. The following year, he settled in the United States. While in the U. In , he opened the School of Vocal Physiology and Mechanics of Speech in Boston, where deaf people were taught to speak.

While teaching, Bell met Mabel Hubbard, a deaf student. The couple married on July 11, They went on to have four children, including two sons who died as infants. In , Bell started working on the harmonic telegraph — a device that allowed multiple messages to be transmitted over a wire at the same time. While trying to perfect this technology, which was backed by a group of investors, Bell became preoccupied with finding a way to transmit human voice over wires. By , Bell, with the help of his partner Thomas Watson, had come up with a simple receiver that could turn electricity into sound.

On March 7, , Bell was granted his telephone patent. Watson, come here. I want you. In , the U. In addition to the telephone, Bell worked on hundreds of projects throughout his career and received patents in various fields. Some of his other notable inventions were:. In , Bell was awarded the French Volta Prize, and with the money, he founded a facility devoted to scientific discovery, the Volta Laboratory in Washington, D. Bell invented numerous techniques to help teach speech to the deaf and even worked with well-known author and activist Helen Keller.

He also helped launch Science magazine , and from to served as president of the National Geographic Society. In , Bell was given the controversial title of honorary president at the Second International Congress of Eugenics. Later in his life, Bell focused on aviation and hydrofoil inventions. Some famous quotes attributed to Bell include:. Bell died on August 2, , at the age of 75 in Nova Scotia, Canada. The cause of his death was complications from diabetes. He was survived by his wife and two daughters.

Today, the famous scientist is remembered for his groundbreaking work in sound technology and improving education for the deaf.
