Re-identified in 2013, Bell made this wax-disc recording of his voice in 1885. Bell’s father, grandfather, and brother had all been associated with work on elocution and speech and both his mother dr graham 80 10 10 pdf 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. Alexander Bell was born in Edinburgh, Scotland, on March 3, 1847. The family home was at 16 South Charlotte Street, and has a stone inscription marking it as Alexander Graham Bell’s birthplace. As a child, young Bell displayed a natural curiosity about his world, resulting in gathering botanical specimens as well as experimenting even at an early age. His best friend was Ben Herdman, a neighbour whose family operated a flour mill, the scene of many forays.

Young Bell asked what needed to be done at the mill. 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. His family was long associated with the teaching of elocution: his grandfather, Alexander Bell, in London, his uncle in Dublin, and his father, in Edinburgh, were all elocutionists. Wikimedia Commons has media related to a young Bell with his parents. As a young child, Bell, like his brothers, received his early schooling at home from his father.

At an early age, he was enrolled at the Royal High School, Edinburgh, Scotland, which he left at the age of 15, having completed only the first four forms. His father encouraged Bell’s interest in speech and, in 1863, took his sons to see a unique automaton developed by Sir Charles Wheatstone based on the earlier work of Baron Wolfgang von Kempelen. Intrigued by the results of the automaton, Bell continued to experiment with a live subject, the family’s Skye Terrier, “Trouve”. Dismayed to find that groundbreaking work had already been undertaken by Helmholtz who had conveyed vowel sounds by means of a similar tuning fork “contraption”, Bell pored over the German scientist’s book. In 1865, when the Bell family moved to London, Bell returned to Weston House as an assistant master and, in his spare hours, continued experiments on sound using a minimum of laboratory equipment.

Helping his father in Visible Speech demonstrations and lectures brought Bell to Susanna E. Hull’s private school for the deaf in South Kensington, London. His first two pupils were deaf-mute girls who made remarkable progress under his tutelage. In 1870, aged 23, Bell, together with Bell’s brother’s widow, Caroline Margaret Ottaway, and his parents travelled on the SS Nestorian to Canada. At the homestead, Bell set up his own workshop in the converted carriage house near to what he called his “dreaming place”, a large hollow nestled in trees at the back of the property above the river. After setting up his workshop, Bell continued experiments based on Helmholtz’s work with electricity and sound.

New Billy Graham outreach: Hosting ‘Matthew parties’ to share the gospel”. And a recipe for creating a new approach to file sharing that’s free from snooping, bell made the first ceremonial transcontinental telephone call.

Throughout his life, he referred to himself as “a teacher of the deaf”. Wikimedia Commons has media related to the Scott Circle School for Deaf Children. Returning home to Brantford after six months abroad, Bell continued his experiments with his “harmonic telegraph”. The basic concept behind his device was that messages could be sent through a single wire if each message was transmitted at a different pitch, but work on both the transmitter and receiver was needed. Unsure of his future, he first contemplated returning to London to complete his studies, but decided to return to Boston as a teacher.

His father helped him set up his private practice by contacting Gardiner Greene Hubbard, the president of the Clarke School for the Deaf for a recommendation. Several influential people of the time, including Bell, viewed deafness as something that should be eradicated, and also believed that with resources and effort, they could teach the deaf to speak and avoid the use of sign language, thus enabling their integration within the wider society from which many were often being excluded. In the following year, Bell became professor of Vocal Physiology and Elocution at the Boston University School of Oratory. During this period, he alternated between Boston and Brantford, spending summers in his Canadian home. At Boston University, Bell was “swept up” by the excitement engendered by the many scientists and inventors residing in the city. Deciding to give up his lucrative private Boston practice, Bell retained only two students, six-year-old “Georgie” Sanders, deaf from birth, and 15-year-old Mabel Hubbard.

Each pupil would play an important role in the next developments. In 1874, telegraph message traffic was rapidly expanding and in the words of Western Union President William Orton, had become “the nervous system of commerce”. In March 1875, Bell and Pollok visited the scientist Joseph Henry, who was then director of the Smithsonian Institution, and asked Henry’s advice on the electrical multi-reed apparatus that Bell hoped would transmit the human voice by telegraph. Henry replied that Bell had “the germ of a great invention”. With financial support from Sanders and Hubbard, Bell hired Thomas Watson as his assistant, and the two of them experimented with acoustic telegraphy. In 1875, Bell developed an acoustic telegraph and drew up a patent application for it.

Since he had agreed to share U. Meanwhile, Elisha Gray was also experimenting with acoustic telegraphy and thought of a way to transmit speech using a water transmitter. On February 14, 1876, Gray filed a caveat with the U. Patent Office for a telephone design that used a water transmitter.
