Our lives today would be very different if Thomas Edison had never lived. Born in 1847, Edison became the most active of all inventors in the late 19th and early 20th centuries. His inventions influenced life all around the world.
Edison’s teachers at school did not recognize his brilliance..In fact, they considered him a rather bad student. Fortunately, his mother thought differently. She took him out of school and taught him at home, which is when he developed his two lifetime passions: reading and experimenting.
His first job was as a telegraph operator, and his first important inventions were improved telegraphic devices. But he first became famous for the phonograph, invented in 1877. Today, in the age of MP3 players, it’s hard to imagine how magical the phonographic recording was. The public loved the new machine and a form of it was used well into the late 20th century.
Edison is often credited as the inventor of the light bulb, though, of course, many people worked on the idea both before and after him. In 1878 he formed the company Edison Electric Light Company and in 1879 introduced his improvements to the incandescent light bulb. At about this time, he became famous for saying, “We will make electricity so cheap that only the rich will burn candles.” His inventions also influenced the development of radiology and the first motion picture cameras.
Edison was proud that he never invented weapons that could be used in warfare, and he strongly believed in nonviolence. But his life was not free from controversy. He was involved in the so-called War of Currents, arguing for the use of direct current (DC) over alternating current (AC).
Edison lived a long life, dying in 1931 at the age of 84. He was married twice and had six children. His many inventions and business ventures made him a very rich man, and a very famous one. Perhaps his most famous quotation is “Genius is one percent inspiration, and ninety-nine percent perspiration.”
