As a young boy, Thomas Alva Edison was already an inventor. The opportunity of a lifetime comes to the newspaper boy when he receives training in telegraphy. Now, his inventive spirit cannot be stopped. Throughout his life, Edison files hundreds of patents, including the carbon filament light bulb that will change the lives of everyone. The man who illuminated the night was a role model for many researchers with his zeal and drive. One of them was Dr. Matthias Meder, who won the national competition "Youth Research" in 1988. He made a brilliant discovery with his friend: luminous bacteria in green herring!.
