The  invention  of the telephone  
The invention of the telephone is the culmination of work done  by many individuals. 
The  presumption  for the  development of the telephone goes back to the  year 1833 were Carl 
Friedrich Gauss and Wilhelm  Eduard Weber   invented the electric  transmission of  signals in 
Göttingen which set the  fundamental basis for the  technology . 
This invention is recognized to be the  first electromagnetic telegraph of the world. 
(The development of the modern telephone involved an array of lawsuits founded upon the 
patent claims of several individuals.) 
Some of the inventors who gave  their  contribution for inventing the telephone are: 
Innocenzo Manzetti - Innocenzo Manzetti  considered the  idea  of a telephone as early  as 1844, 
and may have made one in 1864. He is considered by many Italians as the inventor of the 
telephone. 
Johann Philipp Reis - In 1860 Reis was the first who produced a functioning electromagnetic 
device  that could transmit musical notes , indistinct  speech , and occasionally  distinct speech 
by means of electric signals. 
Antonio Meucci - An early voice communicating device was invented around 1854 by 
Antonio Meucci, (who called it a telettrofono.) In the 1880s Meucci was credited with the 
early invention of inductive loading of telephone wires to increase  long- distance  signals. 
Unfortunately , serious burns from an  accident , a lack of English , and poor  business abilities 
resulted in Meucci failing to develop his inventions commercially in America. 
Alexander Graham Bell is commonly  believed as the inventor of the first practical telephone. 
Bell was born on  March  3, 1847, in Edinburgh, Scotland , and educated at the  universities of 
Edinburgh and London. He immigrated to Canada  in 1870 and to the United States in 1871. 
He was an early student of sound and speech, inspired, perhaps , by the fact that his mother , 
Eliza, was almost totally  deaf and his  father , Melville, developed the first international 
phonetic  alphabet. In his early 20s Bell himself taught deaf children to speak and gave speech 
lessons at schools in his community. 
Bell was the first to obtain a patent, in 1876, for an "apparatus for transmitting vocal or other  
sounds telegraphically", after experimenting with many primitive sound transmitters and 
receivers. 
In 1875, Bell developed his first version of what came to be  known as the telephone. He 
received a patent for it on March 7, 1876, just after his 29th birthday.  Five  days later , on 
March 12, he tested his device, speaking into the phone  to his associate, Thomas Watson , 
when he said, "Mr. Watson, come here. I want to see you." After that this primitive telephone 
was rapidly improved.

successful experiment with the telephone.
