Thomas Edison’s inventions were influenced by a combination of his early experiences, relentless curiosity, and the industrial revolution's technological advancements. Growing up in a financially struggling family, he developed a strong work ethic and a fascination with science and mechanics, which he cultivated through self-education and experimentation. His work as a telegraph operator honed his technical skills and provided insights into electrical systems, ultimately leading him to invent the phonograph, the incandescent light bulb, and numerous other devices that revolutionized communication and energy use. Edison's collaborative environment in his Menlo Park laboratory also fostered innovation, allowing him to refine his inventions through teamwork and experimentation.

Later they came to add "sugar of lead" (now known as lead acetate) for this same purpose. Burnt bread, or what we ,today call burnt toast, was also used to flavor the wine, in additions to herbs and spices.
