who invented telephone??!!?

Ask who really invented the telephone, and you may get the name of a German, Philipp Reis, not Alexander Graham Bell. \n\nReis was a 26-year-old science teacher when he began work on the telephone in 1860. His essential idea came from a paper by a French investigator named Bourseul. In 1854 Bourseul had explained how to transmit speech electrically. He wrote: \n\nSpeak against one diaphragm and let each vibration "make or break" the electric contact. The electric pulsations thereby produced will set the other diaphragm working, and [it then reproduces] the transmitted sound. \n\nConcept might be from Philipp Reis in 1860.\nAn invented telephone was from Alexander Graham Bell in 1876.

I called a friend on his cell phone, and he answered "How did You know I was here??".......Dumb Ass...!!!

Isn't that rude? I think that the very concept behind cell phones is to be as connected as possible, and I guess that means calling someone AS SOON AS YOU CAN!

Optical communication systems date back to the 1790s, to the optical semaphore telegraph invented by French inventor Claude Chappe. In 1880, Alexander Graham Bell patented an optical telephone system, which he called the Photophone. However, his earlier invention, the telephone, was more practical and took tangible shape. The Photophone remained an experimental invention and never materialized. During the 1920s, John Logie Baird in England and Clarence W. Hansell in the United States patented the idea of using arrays of hollow pipes or transparent rods to transmit images for television or facsimile systems. \n\nIn 1954, Dutch scientist Abraham Van Heel and British scientist Harold H. Hopkins separately wrote papers on imaging bundles. Hopkins reported on imaging bundles of unclad fibers, whereas Van Heel reported on simple bundles of clad fibers. Van Heel covered a bare fiber with a transparent cladding of a lower refractive index. This protected the fiber reflection surface from outside distortion and greatly reduced interference between fibers.\n\nAbraham Van Heel is also notable for another contribution. Stimulated by a conversation with the American optical physicist Brian O'Brien, Van Heel made the crucial innovation of cladding fiber-optic cables. All earlier fibers developed were bare and lacked any form of cladding, with total internal reflection occurring at a glass-air interface. Abraham Van Heel covered a bare fiber or glass or plastic with a transparent cladding of lower refractive index. This protected the total reflection surface from contamination and greatly reduced cross talk between fibers. By 1960, glass-clad fibers had attenuation of about 1 decibel (dB) per meter, fine for medical imaging, but much too high for communications. In 1961, Elias Snitzer of American Optical published a theoretical description of a fiber with a core so small it could carry light with only one waveguide mode. Snitzer's proposal was acceptable for a medical instrument looking inside the human, but the fiber had a light loss of 1 dB per meter. Communication devices needed to operate over much longer distances and required a light loss of no more than 10 or 20 dB per kilometer.\n\nBy 1964, a critical and theoretical specification was identified by Dr. Charles K. Kao for long-range communication devices, the 10 or 20 dB of light loss per kilometer standard. Dr. Kao also illustrated the need for a purer form of glass to help reduce light loss. \n\nIn the summer of 1970, one team of researchers began experimenting with fused silica, a material capable of extreme purity with a high melting point and a low refractive index. Corning Glass researchers Robert Maurer, Donald Keck, and Peter Schultz invented fiber-optic wire or "optical waveguide fibers" (patent no. 3,711,262), which was capable of carrying 65,000 times more information than copper wire, through which information carried by a pattern of light waves could be decoded at a destination even a thousand miles away. The team had solved the decibel-loss problem presented by Dr. Kao. The team had developed an SMF with loss of 17 dB/km at 633 nm by doping titanium into the fiber core. By June of 1972, Robert Maurer, Donald Keck, and Peter Schultz invented multimode germanium-doped fiber with a loss of 4 dB per kilometer and much greater strength than titanium-doped fiber. By 1973, John MacChesney developed a modified chemical vapor-deposition process for fiber manufacture at Bell Labs. This process spearheaded the commercial manufacture of fiber-optic cable.\n\nIn April 1977, General Telephone and Electronics tested and deployed the world's first live telephone traffic through a fiber-optic system running at 6 Mbps, in Long Beach, California. They were soon followed by Bell in May 1977, with an optical telephone communication system installed in the downtown Chicago area, covering a distance of 1.5 miles (2.4 kilometers). Each optical-fiber pair carried the equiva

This probably is of little practical value, since I haven't seen the product I speak of for years.  But it is an idea that might prompt something useful.\n\nThere used to be a product called Call Manager I.  You installed this between the line to the phone company and the phones in your home.  Phones would operate normally.  To call someone on the intercom, you'd pick up a phone and "flash" it.  (quickly press-release a button in the cradle or push the flash button or turn the phone on, then off then on.)  The phone would then emit a noise.   You would then dial 1 -- 1, 2, 3, 4 or 5 times and hang up.  All phones would then start ringing a ring code -- short, short short, short short short, short long or long short.  The person who recognized his ring would pick up.  You, upon hearing the ringing stop, would pick up.  Talk to each other and hang up.\n\nIt also acted as a call forwarding device.  While on a call to an outsider, you could "flash" the phone, enter the code of the person to transfer to and hang up.\n\nFantastic device.  I have one and love it.

There was a previous generation or two of mobile phones before the cellular phones we know have. Cellular phones were developed to increase the capacity of the system, since there was not enough bandwidth available to give service to everyone who might want it.\n\nIt is hard to say who first invented the mobile phone. It is a matter of definition, since it overlaps with the invention of radio, depending on how you define a phone. \nSome claim that the dentist Mahon Loomis of Virginia transmitted radio signals first in 1865. David Hughes in 1879 demonstrated what might be the first radio telephone. \n\nThere is a lot more information in the references. I am not sure where you draw the line exactly and say, THIS was the first mobile phone. \n\nWas it Bell Labs in 1924, in their first two war car radio phone? Or was it not until 1947, when commercial systems were available? Or Motorolla's Martin Cooper, who made a famous phone call on a portable cell phone to his rival  at Bell Labs in 1973?

Since this assignment came from your Communications Class, I would imagine that it should have something to do with Communication.  So why not do a project on the telephone from it's invention until today's cell phones.  Do some research on Alexander Graham Bell for lots of information.  If you have to create something to go along with your written information, you could always find instructions on the internet for creating your own telephone.  Such as attaching two tin cans with a very long piece of string so that 2 people can talk to each other by listening and talking into each can.\n"Take two tin cans with one end removed from each. Punch a whole in the center of the intact end of each can. With a long piece of string, thread the two cans so that their flat ends face each other. Tie knots in the ends of the string. Pull the string tight, so that it is stretched between the two cans. Talk into one can; have someone else listen at the other."\nHere's a website with some information on Alexander Graham Bell; http://www.privateline.com/TelephoneHistory/History1.htm\nHere's a website with some information on the first cell phone;\nhttp://inventors.about.com/cs/inventorsalphabet/a/martin_cooper.htm\nHope this helps answer your question.

No president invented the concept of spying on telephone calls but Woodrow Wilson gets credit for being the first to authorize the interception of all cabled messages to and from Europe during World War 1. Herbert Hoover used wiretaps during his war on bootleggers during the twenties prompting the creation of the communications act in 1934 that Franklin Roosevelt ignored during World War two saying it didn't apply to threats of national security. Sound familiar? Truman authorized wiretapping during his hunt for communists. Kennedy and Johnson both tapped Martin Luther King's phones saying he had ties to communism and was a threat to national security. Nixon ordered his brother's phones tapped! Republican or Democrat presidents will find excuses to get around the bill of rights they take oaths to defend.\n\nVin

Antonio Meucci an Italian, never got a backer for his patented invention of the telectrophone. Later Alexander Graham Bell invented the telephone and had it patented.\n\n"On March 7, 1876, the U.S. Patent Office granted Bell a patent for a communication device for "transmitting vocal or other sounds telegraphically." However, on September 25, 2001, the United States Congress officially recognized Antonio Meucci as the inventor of the telephone, denying Bell's claim to its invention."

AHOY!using the word ''hello''as a greeting only as old as the telephone invented by alexander graham bell in 1876. alexander graham bell suggested that people say ''ahoy'' when they answered a ring, but this doen't catch on. ''hello'' caught on instead. it is related to ''hallo'', a cry of surprise in the mid-19th century

-07-27: No one person invented the Internet as we know it today. However, certain major figures contributed major breakthroughs: \nLeonard Kleinrock was the first to publish a paper about the idea of packet switching, which is essential to the Internet. He did so in 1961. Packet switching is the idea that packets of data can be "routed" from one place to another based on address information carried in the data, much like the address on a letter. Packet switching replaces the older concept of "circuit switching," in which an actual electrical circuit is established all the way from the source to the destination. Circuit switching is the idea behind traditional telephone exchanges. \n\nJ.C.R. Licklider was the first to describe an Internet-like worldwide network of computers, in 1962. He called it the "Galactic Network." \n\nLarry G. Roberts created the first functioning long-distance computer networks in 1965 and designed the Advanced Research Projects Agency Network (ARPANET), the seed from which the modern Internet grew, in 1966. \n\nBob Kahn and Vint Cerf invented the Transmission Control Protocol (TCP) which moves data on the modern Internet, in 1972 and 1973. \n\nBy 1983, TCP was the standard and ARPANET began to resemble the modern Internet in many respects. The ARPANET itself was taken out of commission in 1990. Most restrictions on commercial Internet traffic ended in 1991, with the last limitations removed in 1995. \n\nFor a much more complete history, see the web site of the Internet Society. \n\nNote that the Internet and the World Wide Web are not the same thing. See also: who invented the World Wide Web?, What is the difference between the World Wide Web and the Internet? and See also Hobbes' Internet Timeline for another excellent history of the Internet which includes later important events. \n\nNOTE TO STUDENTS: THE INTERNET WAS NOT INVENTED BY ONE PERSON OR GROUP OF PEOPLE. THERE IS NO ONE INDIVIDUAL RESPONSIBLE. I get a lot of email about this. If I gave you just one name, my answer would be completely wrong. Writing down one name on a test will probably get you a bad grade. If your teacher says that one person invented the Internet, show them this page. And don't forget, the Internet and the World Wide Web are NOT the same thing. See What is the difference between the World Wide Web and the Internet?

Milatary radios were probably first with that. In the year 2006 every cell phone company in the world will have it.

Alexander Graham Bell (March 3, 1847 – August 2, 1922) was a Scottish-born scientist and inventor. Today, Bell is still widely considered to be the foremost inventor of the telephone, although this matter has become controversial, with a number of people claiming that Antonio Meucci was the "real" inventor (in June 2002, the United States House of Representatives passed a symbolic bill officially recognizing Meucci for his contributions to the invention of the telephone).\n\nMore at: http://en.wikipedia.org/wiki/Alexander_Graham_Bell\n\nor\n\nhttp://inventors.about.com/library/inventors/bltelephone2.htm\n\nor\n\nhttp://www.invent.org/hall_of_fame/11.html

read the whole of this link. he invented and patented some kind of paper clip - but maybe not the type that was eventually produced. Most people regard it as a myth that he invented the paper clip - except the Norwegians apparently. Read the wikipedia stuff.

He worked for Alexander Graham Bell and Thomas Watson, and  was their draftsman who drew up the telephone invention for the patent application.  He was also an inventor who teamed up with W.C. Brown to design improvements to bathrooms on trains.  He also worked with Thomas Edison and Hiram Maxim.   for a while.
