I don't think so, c below:-\n\nnvention:   flashlight in 1902   \nDefinition:  noun / flash·light, flashlight, flash-light\nFunction:  a small portable battery-powered electric lamp, typically flashlight consists of a small electric light bulb with associated parabolic reflector, powered by electric batteries, and with an electric power switch\nPatent:  737,107 (US) issued August 26, 1903\nInventor:  Conrad Hubert (aka Akiba Horowitz)   \nCriteria:  First practical. Modern prototype. Entrepreneur.\nBirth:  April 15, 1856 in Minsk, Russia\nDeath:  1928\nNationality:  American (of Russian decent)\n Akiba Horowitz born on April 15, 1856 in Minsk, Russia came to the United States in 1891 and changed his name to Conrad Hubert. He was flat broke. He did what he could to earn a living.  He worked in a cigar store, ran a restaurant for a while and managed a boarding house. He even tried repairing watches. Whatever he did, however, he never made much money. All he wanted was to stop worrying about making ends meet.

The invention of the incandescent light bulb has a history spanning from the early 1800s. Until that time, available light sources consisted of candles, oil lanterns, and gas lamps. \n\nIn 1809, an English chemist, Humphrey Davy, started the journey to the invention of a practical incandescent light source. He used a high power battery to induce current between two charcoal strips. The current flowing through the two charcoal strips produced an intense incandescent light, creating the first arc lamp. \n\nIn 1820, Warren De la Rue made the first known attempt to produce an incandescent light bulb. He enclosed a platinum coil in an evacuated tube and passed an electric current through it. The design was based on the concept that the high melting point of platinum would allow it to operate at high temperatures and that the evacuated chamber would contain less gas particles to react with the platinum, improving its longevity. Although it was an efficient design, the cost of the platinum made it impractical for commercial use.\n\nThe invention of the light bulb is usually attributed in Britain to Joseph Wilson Swan and in the United States to Thomas Alva Edison(and his asstant Timothy) (the first to market the device successfully). Alexander Nikolayevich Lodygin independently developed an incandescent light bulb in 1874. Many others also had a hand in the development of a practical device for the production of electric light.

Michael Farday invented electricity as we know it.\nAs a sidenote If Benny Franklin was  a creator of anything it was the lightning rod and the grounding priciple.\nFor centuries electricity has been a challenge to scientists. They have long known that it exists, and have discovered how to generate it on a large scale, but find it difficult to explain exactly what electricity is.\n\nWhere did it all begin?\n\nAround 600 BC Greeks found that by rubbing an 'electron' (a hard Fossilised resin that today is known as Amber) against a fur cloth, it would attract particles of straw. This strange effect remained a mystery for over 2000 years, until, around AD 1600, Dr William Gilbert investigated the reactions of amber and magnets and first recorded the word 'Electric' in a report on the theory of magnetism.\n\nGilbert's experiments led to a number of investigations by many pioneers in the development of electricity technology over the next 350 years.\n\nBenjamin Franklin(in his own words)\n Franklin was an American writer, publisher, scientist and diplomat, who helped to draw up the famous Declaration of Independence and the US Constitution. In 1752 Franklin proved that lightning and the spark from amber were one and the same thing. The story of this famous milestone is a familiar one, in which Franklin fastened an iron spike to a silken kite, which he flew during a thunderstorm, while holding the end of the kite string by an iron key. When lightening flashed, a tiny spark jumped from the key to his wrist. The experiment proved Franklin's theory, but was extremely dangerous - He could easily have been killed.\n\nGalvani and Volta\n In 1786, Luigi Galvani, an Italian professor of medicine, found that when the leg of a dead frog was touched by a metal knife, the leg twitched violently. Galvani thought that the muscles of the frog must contain electricity. By 1792 another Italian scientist, Alessandro Volta, disagreed: he realised that the main factors in Galvani's discovery were the two different metals - the steel knife and the tin plate - apon which the frog was lying. Volta showed that when moisture comes between two different metals, electricity is created. This led him to invent the first electric battery, the voltaic pile, which he made from thin sheets of copper and zinc separated by moist pasteboard.\n\nIn this way, a new kind of electricity was discovered, electricity that flowed steadily like a current of water instead of discharging itself in a single spark or shock. Volta showed that electricity could be made to travel from one place to another by wire, thereby making an important contribution to the science of electricity. The unit of electrical potential, the Volt, is named after Volta.\n\nMichael Faraday\n The credit for generating electric current on a practical scale goes to the famous English scientist, Michael Faraday. Faraday was greatly interested in the invention of the electromagnet, but his brilliant mind took earlier experiments still further. If electricity could produce magnetism, why couldn't magnetism produce electricity.\n\nIn 1831, Faraday found the solution. Electricity could be produced through magnetism by motion. He discovered that when a magnet was moved inside a coil of copper wire, a tiny electric current flows through the wire. Of course, by today's standards, Faraday's electric dynamo or electric generator was crude, and provided only a small electric current be he discovered the first method of generating electricity by means of motion in a magnetic field.\nThomas Edison and Joseph Swan\n Nearly 40 years went by before a really practical DC (Direct Current) generator was built by Thomas Edison in America. Edison's many inventions included the phonograph and an improved printing telegraph. In 1878 Joseph Swan, a British scientist, invented the incandescent filament lamp and within twelve months Edison made a similar discovery in America.\n\nSwan and Edi

Thomas Edison is credited with creating the incandescent light bulb. He, however, did not create it from scratch. He improved on the designs of others. He also created the generating system to power the bulbs.

I heard it said that Thomas Edison said, after failing 10,000 time to successfully invent the light bult, "I have discovered 10,000 ways this will not work."\n\nMy point is this.  You'll come out wiser, or foolish for having missed the opportunity.
