A method of burning coal as a fuel in making iron was developed in the 1830's. Demand for iron in manufacturing was very high. As American industry became able to make it's own iron, industries that made machines, farm tools, rails, and parts of railroad cars grew very quickly.
What were Thomas Edison's first words over the telephone?
The first words ever spoken on a telephone were, " Mr. Watson! Come here! I need you!" spoken by Alexander Gram Bell, who at the time, had just spilled acid on himself while testing his new invention.
Very true.
What was the first thing ever filmed?
Ignoring still photography, the first 'film'; multi-frames intended to show motion, was filmed by: Eadweard J. Muybridge, the film or series of pictures was of a horse galloping (June 11, 1877) - it consisted of 24 frames, although less actually survived time.
When and where did Thomas Jefferson invent the light-bulb?
Thomas Jefferson did not invent the light bulb.
The light bulb was invented by Thomas Edison in 1879 in New Jersey.
What are Thomas Edison accomplishments?
Thomas Edison is famous for inventing the first long-lasting light bulb.
Although he also invented the motion picture camera, the phonograph, and a lot of other great inventions.
Thomas Edison's greatest challenge was the development of a practical incandescent, electric light. Contrary to popular belief, he didn't "invent" the lightbulb, but rather he improved upon a 50-year-old idea. In 1879, using lower current electricity, a small carbonized filament, and an improved vacuum inside the globe, he was able to produce a reliable, long-lasting source of light. So he said. Tesla worked for Thomas Alva Edison for 1 year At that time, the most important "inventor" in the world was named Thomas Alva Edison-the so-called wizard of Menlo Park.... Edison was credited with the invention of the DC dynamo and the electric light bulb . . . but the only thing he really invented was the ELECTRIC CHAIR!!
When was the telegraph invented?
There were several steps towards the invention of the telegraph.
- The non-electric telegraph was invented in 1794 by Claude Chappe. This system used semaphore, rather than electrical signals along a wire, as later telegraphs did.
- A simple form of electric telegraph using liquid and the concept of electrolysis was invented in 1809 by Samuel Soemmering of Bavaria. This was not a commercially viable product, but it showed how electrical signals could be transmitted.
- In 1825 William Sturgeon invented the electromagnet, which would later play a big part in the transmission of signals via telegraphs.
- In 1830, Joseph Henry used Sturgeon's concept of the electromagnet to send communication signals along a wire.
- The electric telegraph itself, which came to be the mainstay of 19th century communications, was investigated and improved upon from around 1835 by Samuel F B Morse. In 1843, the first experimental telegraph line from Washington to Baltimore was constructed, using Morse's concepts.
- In 1893, the wireless telegraph was invented by Guglielmo Marconi.
How did Edison and Tesla know each other?
Nikola Tesla worked for Edison making the Edison Direct currrent machine workable because Edison and his scientists could not make it work properly. Edison was not good to his word and negleted the promise money he offered. Nikola parted his way and now we have his inventions.
Did Edison steal inventions from tesla?
Edison is known for the most stolen patents in history. He did work the direct current motor but it caused a lot of problem. People got electrocuted and there were many fires caused by that. Tesla fixed the problem but Edison did not pay sum offered.
Did Thomas Edison have any royal relatives?
There are of course many people related through grandparents, great-grandparents, etc., myself being one of them. I don't know exactly if any direct descendants are currently living.
When did Thomas Edison sell his light bulb?
He didn't. Edison improved the light bulb, but was not the one who first designed it. Scottish inventor James Bowman Lindsay is generally viewed as the inventor of the bulb sometime in the 1830s.
Edison's patent for the "Improvement In Electric Lights" was filed on 14 October 1878, many years after the first rudimentary light bulbs were made.
What was the war of currents of thomas Edison and Nikola Tesla?
Tesla and Edison became involved with this issue since Edison was working in the monopoly of the electric system based on his direct current system. Using direct current to light houses is more costly and dangerous that using alternant current. So, Tesla won the war.
If Edison had a needle to find in a haystack, he would proceed at once with the diligence of the bee to examine straw after straw until he found the object of his search. ... I was a sorry witness of such doings, knowing that a little theory and calculation would have saved him ninety per cent of his labor.

Influence of modern technologies on students?
A negative effect of these gadgets on students can be the fact that they can become obsessive and the students can neglect everything else, like their social life, their family and friends. Is not a bad thing to have a computer, but is a bad thing to spend all your life in front of it pretending that everything else doesn't exist.
Otherwise, most gadgets have positive effects because they enable us to do things faster and easier and they are also good when it comes to learning new things.
How did the invention of the light bulb change your lives?
Lightbulbs were easy to turn on and keep on.
Thomas Alva Edisson invented the Electric bulb Among all of his other inventions, the invention of electric bulb was the most revolutionary without which the entire work force on earth would have been dependent on daylight or oil lamps etc
Who made the first light bulb?
The first electric light was made in 1800 by Humphry Davy.
Then the inventor Thomas Alva Edison (in the USA) experimented with thousands of different filaments to find just the right materials to glow well and be long-lasting. In 1879, Edison discovered that a carbon filament in an oxygen-free bulb glowed but did not burn up for 40 hours. Edison eventually produced a bulb that could glow for over 1500 hours.

Who was credited for the invention of the light bulb?
Though people claim Edison invented the light bulb, it was previously discovered by many inventors which includes Nikola Tesla. But Edison found a way where everyone could use it and hence Edison has been credited for the invention of the light bulb.
Why did Thomas Edison start inventing?
Thomas Edison didn't invent the light bulb.
Thomas Edison improved the light bulb design because he went to a convention and saw a lightbulb realitive to the one he will soon copy. But it went out in a few minutes.
What was Thomas Edison's second invention?
In 1915, aged 68, he invented the first synthetic form of carbolic acid (C6H6O).
He died in 1931, aged 84, in New Jersey, USA.
Who helped Thomas Edison accomplish his goals?
Edison had a large and talented staff working full time at Menlo Park. Men like Nikola Tesla had worked for Edison but left his employ when he felt that Edison neither appreciated or rewarded his inovations.
What was the first invention Thomas Edison made?
It is pretty much agreed that the first invention of Thomas Edison was a tin foil phonograph. The idea came to him while working to improve the efficiency of the telegraph. He noticed that if the telegraph sounds were played at a high rate of speed the sounds resembled words.
What did Thomas Edison contribute to the world?
Actually he did not invent the lightbulb, he only improved on it making it practical and inexpensive.
His real impact on electrical technology was to invent the infrastructure (e.g. large generators, distribution grid, electric usage meters, fuse boxes, light switches, light sockets) needed to support those lightbulbs so that people could depend on them working when needed.
The creation and maintenance of this infrastructure for the first time was of far greater significance than the invention of lightbulbs or his perfection of lightbulbs.
Why is Thomas Edisons electric pen important?
one of the greatest inventors of all time no one like him... in history most people invent 1 or 2 things but Thomas Alva Edison is the biggest inventor because he invented more than 1000 products..(1038) so he is the real legend but
another important thing is that he is not very good in acadamics, he left school at the age 10 so he would do his research and studying all on his own, and mad inventions through his own ideas..
What inventions did Thomas Edison make which we still use today?
Yes he ivented lightbulbs" and we still use them.
