Thomas Edison is usually credited with the invention of the light bulb, but the famous American inventor wasn't the only one who contributed to the development of this revolutionary technology. Many notable figures are also remembered for their work with electric batteries, lamps and the creation of the first incandescent bulbs.
Early research & developments
The story of the light bulb begins long before Edison patented the first commercially successful bulb in 1879. In 1800, Italian inventor Alessandro Volta developed the first practical method of generating electricity, the voltaic pile. Made of alternating discs of zinc and copper — interspersed with layers of cardboards soaked in salt water — the pile conducted electricity when a copper wire was connected at either end. While actually a predecessor of the modern battery, Volta's glowing copper wire is also considered to be one of the earliest manifestations of incandescent lighting.
Not long after Volta presented his discovery of a continuous source of electricity to the Royal Society in London, an English inventor named Humphrey Davy produced the world's first electric lamp by connecting voltaic piles to charcoal electrodes. Davy's 1802 invention was known as an electric arc lamp, named for the bright arc of light emitted between its two carbon rods.
The Greatest Invention In My EyesGood evening, ladies and gentlemen. Last night in my room, busy preparing for my speech today, I was puzzled at the opinions of greatest inventions of different persons. I read many books. Some articles hold the opinions that the greatest invention in the world is electricity, while the others believe computers cannot be replaced in the modern society. I read and read, suddenly an idea struck me: The greatest invention are just books. A famous person has ever said: "Books are the best teachers." Exactly! That's what I would like to say firstly. In the long history of human being, books have played an important part in communicating knowledge. And even today, the situation is still so. Each year, millions of books are published in the world. Knowledge changes our lives.

the telephone is an instrument that converts voice and sound signals into electrical impulses for transmission by wire to a different location, where another telephone receives the electrical impulses and turns them back into recognizable sounds. in 1875, alexander graham bell built the first telephone that transmitted electrically the human voice.
when bell began experimenting with electrical signals, the telegraph had been an established means of communication for some 30 years. although a highly successful system, the telegraph, with its dot-and-dash morse code, was basically limited to receiving and sending one message at a time. bell's extensive knowledge of the nature of sound and his understanding of music enabled him to conjecture the possibility of transmitting multiple messages over the same wire at the same time. although the idea of a multiple telegraph had been in existence for some time, bell offered his own musical or harmonic approach as a possible practical solution. his "harmonic telegraph" was based on the principle that several notes could be sent simultaneously along the same wire if the notes or signals differed in pitch.
