how did alexander graham bell invent the telephone

Here are some the things he invented: The Metal Detector - Bell invented the first metal detector which was used to try and find a bullet inside of President James Garfield. [176], In November 1883, Bell presented a paper at a meeting of the National Academy of Sciences titled "Upon the Formation of a Deaf Variety of the Human Race". 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 1873. Having lost her hearing after a near-fatal bout of scarlet fever close to her fifth birthday,[74][75][N 11] she had learned to read lips but her father, Gardiner Greene Hubbard, Bell's benefactor and personal friend, wanted her to work directly with her teacher. Bell's father was invited by Sarah Fuller, principal of the Boston School for Deaf Mutes (later to become the public Horace Mann School for the Deaf)[56] to introduce the Visible Speech System by providing training for Fuller's instructors, but he declined the post in favour of his son. [183], Bell died of complications arising from diabetes on August 2, 1922, at his private estate in Cape Breton, Nova Scotia, at age 75. On March 7, 1876, the Patent Office awarded Bell what is said to be one of the most valuable patents in history. [172], Bell, along with many members of the scientific community at the time, took an interest in the popular science of heredity which grew out of the publication of Charles Darwin's book On the Origin of Species in 1859. 2 Thanks to his contributions, communications continue to expand and improve across the globe, allowing people to stay connected from virtually anywhere. He wanted to use this to help teach deaf people, who had never heard spoken words, to speak. Bell's patent covered "the method of, and apparatus for, transmitting vocal or other sounds telegraphically by causing electrical undulations, similar in form to the vibrations of the air accompanying the said vocal or other sound"[86][N 14] Bell returned to Boston the same day and the next day resumed work, drawing in his notebook a diagram similar to that in Gray's patent caveat. He said, "Mr. Watson, come here I want to see you" and Watson soon appeared at his side.

[N 22][N 23] The innovations that were incorporated into this design included a cockpit enclosure and tail rudder (later variations on the original design would add ailerons as a means of control). In our new video series, Ingenious, Susannah Carroll and Trace Dominguez look at the history of many inventions that have changed our world - including the telephone.Most people know Alexander Graham Bell as the inventor of the telephone, but there is so much more to that story. [175] This interest in animal breeding caught the attention of scientists focused on the study of heredity and genetics in humans. The story of Alexander Graham Bell and Canada's greatest invention is told in one teen pop song. [113] The Bell company lawyers successfully fought off myriad lawsuits generated initially around the challenges by Elisha Gray and Amos Dolbear. "[177], A review of Bell's "Memoir upon the Formation of a Deaf Variety of the Human Race" appearing in an 1885 issue of the "American Annals of the Deaf and Dumb" states that "Dr. Bell does not advocate legislative interference with the marriages of the deaf for several reasons one of which is that the results of such marriages have not yet been sufficiently investigated." Although Alexander Graham Bell is best remembered as the inventor of the telephone, he invented other devices too. The following night, he amazed guests as well as his family with a call between the Bell Homestead and the office of the Dominion Telegraph Company in Brantford along an improvised wire strung up along telegraph lines and fences, and laid through a tunnel. GRAHAM BELL BIRTH ANNIVERSARY: Alexander Graham Bell, popularly known by his middle name Graham Bell, is known for his contribution to the invention of telephone.He was born on March 3 in 1847, in Scotland and moved to Canada with his family. At the age of eleven he chose to add the middle name. On March 3, 1847, Alexander Graham Bell was born, the man who is credited in popular culture with the invention of the first working telephone. Alexander Graham Bell was born into a family that was preoccupied with sound. [96][97] The final test certainly proved that the telephone could work over long distances, at least as a one-way call. When Bell said that he did not have the necessary knowledge, Henry replied, "Get it!" [52][N 8] He continued his interest in the study of the human voice and when he discovered the Six Nations Reserve across the river at Onondaga, he learned the Mohawk language and translated its unwritten vocabulary into Visible Speech symbols. [166], Bell was a supporter of aerospace engineering research through the Aerial Experiment Association (AEA), officially formed at Baddeck, Nova Scotia, in October 1907 at the suggestion of his wife Mabel and with her financial support after the sale of some of her real estate. In 1881 they successfully sent a photophone message nearly 200 metres between two buildings. The result was a contraption that he dubbed the ear phonautograph. A person could speak into the machine, and a pen attached to a membrane would react by tracing a line. This time, guests at the household distinctly heard people in Brantford reading and singing. [127] The establishment of the International Bell Telephone Company in Brussels, Belgium in 1880, as well as a series of agreements in other countries eventually consolidated a global telephone operation. Following the death of both of Bells brothers from tuberculosis, in 1870 the family emigrated to start a healthier life in Canada.

ALEXANDER GRAHAM BELL invented the telephone. In later years, Bell described the invention of the telephone and linked it to his "dreaming place". After the hard work of Bell and his team, the first message of Alexander Graham Bell was delivered to his assistant Mr. Watson. His main interest remained in the sciences, especially biology, while he treated other school subjects with indifference, to the dismay of his father. Over the course of more than 30 years, Bell sought to produce a breed of sheep with multiple nipples that would bear twins. From his early years, Bell showed a sensitive nature and a talent for art, poetry, and music that was encouraged by his mother. In the 1830s he moved to Cuba and, while working on methods to treat illnesses with electric shocks, found that sounds could travel by electrical impulses through copper wire. He supported the journal Science, which later became the official publication of the American Association for the Advancement of Science. [197] During his life, he also received dozens of major awards, medals, and other tributes. [citation needed], Bell's own home used a primitive form of air conditioning, in which fans blew currents of air across great blocks of ice. Bell considered the photophone "the greatest invention [he had] ever made, greater than the telephone." By then, the Bell company no longer wanted to sell the patent. page 1 of 3. [128][N 17]. Prior to perfecting the telephone, Alexander Graham Bell invented and demonstrated the harmonic telegraph at the Centennial Exposition of 1876, held in Philadelphia's Fairmount Park. [131] One unusual request exacted by his fiance was that he use "Alec" rather than the family's earlier familiar name of "Aleck". [citation needed], Emperor Pedro II of Brazil was the first person to buy stock in Bell's company, the Bell Telephone Company. [N 2] Bell considered his invention an intrusion on his real work as a scientist and refused to have a telephone in his study. Alexander Graham Bell was the first to secure a patent for the telephone, but only just. Married. According to some accounts, the metal detector worked flawlessly in tests but did not find Guiteau's bullet, partly because the metal bed frame on which the President was lying disturbed the instrument, resulting in static. [110], As is sometimes common in scientific discoveries, simultaneous developments can occur, as evidenced by a number of inventors who were at work on the telephone. Although he was enrolled as a student in Latin and Greek, he instructed classes himself in return for board and 10 per session. Bell and assistant Frederick W. "Casey" Baldwin began hydrofoil experimentation in the summer of 1908 as a possible aid to airplane takeoff from water. [70] Although, in his memoir Memoir upon the Formation of a Deaf Variety of the Human Race, Bell observed that if deaf people tended to marry other deaf people, this could result in the emergence of a "deaf race". [189] He was survived by his wife Mabel, his two daughters, Elsie May and Marian, and nine of his grandchildren. During the 1890s Bell shifted his attention to heavier-than-air flight. [111] Over a period of 18 years, the Bell Telephone Company faced 587 court challenges to its patents, including five that went to the U.S. Supreme Court,[112] but none was successful in establishing priority over the original Bell patent[113][114] and the Bell Telephone Company never lost a case that had proceeded to a final trial stage. AMBLF 503 Washington Ave. # 186Chestertown, MD 21620. George's father, Thomas Sanders, a wealthy businessman, offered Bell a place to stay in nearby Salem with Georgie's grandmother, complete with a room to "experiment".

Bell Dead. The 150th anniversary of Bell's birth in 1997 was marked by a special issue of commemorative 1 banknotes from the Royal Bank of Scotland. He attended classes in anatomy and physiology in London for several years, building his understanding of how speech and hearing worked. On the morning of February 14, 1876, a representative for Alexander Graham Bell handed in a patent application to the patent office in Washington for an apparatus for transmitting vocal sounds via electricity lines.
