What is the greatest invention of all time?
. There are many different possible world’s greatest inventions because they have all helped out humankind in some way, some more than others. I think that the greatest invention of all time is Harnessed Electricity. Some may argue that this was not an invention it was a discovery but although electricity itself was a discovery there was still the invention of had to use it and what it could be used for. I think that electricity is very important to human life because it would be nearly impossible to do anything we do today. We all know that Thomas Alva Edison was the discover of the electricity who was born in 1847. Thomas Edison only had 3 months of formal education, and his schoolmaster thought that Edison may have been retarded. And no one not even his family could envision that Edison would become the inventor that he would eventually end up to be. Born in Milan, Ohio, youngest of 7 children, Edison would often ask questions that his father and mother both could not answer. At 21 Edison made his commercial debut as an inventor with an electric vote-recorder. It did not sell so thereafter he decided to concentrate his efforts on inventions that he was sure would be in universal demand. Then in 1869 Edison arrived in Boston, he persuaded a broker to let him sleep in his office. Then when the broker’s stock ticker broke Edison was able to repair it where many others had failed. Amazed the manager quickly made Edison one of his superiors.Soon, Edison had enough money to open his own workshop known as Menlo Park, it was here that some of his most important inventions were created. Of these were Modernized type writer, a practical telephone, the first working model phonograph, an incandescent light. Eventually Edison would also design the first power station, providing electricity for millions of homes. His last contribution a synthetic rubber made from goldenrod plants.
