Who made lightbulbs

Leonardo da Vinci invented the light bulb in 1978. Leo said that it came to him in his sleep, and he wrote it down. Later the next day Leo found the note that he had written and got to work right away. Leo plotted and schemed. Finally, Leo went out at night and snuck into an electronics store at 1 am, grabbed the materials he needed and went home. He worked for 38 hours straight then passed out on the floor when Leo came to he looked up and saw his project finished he plugged it in and sure enough it worked. Leo started to sell his product. Leo could not keep up with the demand so he made a factory with all of his income. Prices soared and he became one of the richest people in the world. But sadly he was not a good businessman. Soon enough people stopped buying. His profits plummeted, and he lost all of his money, in the end he lost everything.
