Thomas Alva Edison was born on February 11, 1847, in Milan, Ohio. He was the youngest of seven children, and his family life was modest. His father, Samuel, was a shingle maker and land speculator, while his mother, Nancy, was a former schoolteacher. From a young age, 'Al,' as his family called him, was endlessly curious. He was known for asking 'why' about everything.

Edison's formal schooling was brief. After just three months, his teacher labeled him 'addled,' or confused, because he was so energetic and distracted. His mother, confident in her son's abilities, pulled him out of school and decided to teach him at home. This turned out to be a blessing. It allowed his curiosity to flourish without the strict structure of a classroom. Nancy Edison encouraged him to read widely, and he devoured books on science and history.

A bout of scarlet fever as a child left him with severe hearing problems, making him nearly deaf. Rather than seeing this as a disability, Edison often treated it as an asset. He found it easier to concentrate on his experiments and reading without the distraction of outside noise. He spent much of his childhood conducting chemistry experiments in his basement, a passion that sometimes got him into trouble but laid the groundwork for his future career.

Edison didn't just love learning; he also had a sharp business sense from an early age. At 12, he took a job selling newspapers and candy on the Grand Trunk Railroad line that ran from Port Huron, Michigan, to Detroit. This wasn't just a simple job. It was a mobile business enterprise.

He set up a small lab in a baggage car to conduct experiments during the long train rides. He also saw an opportunity to provide news faster. He bought a small, secondhand printing press and began publishing his own newspaper, the Weekly Herald. It was the first newspaper ever published on a moving train. He sold it to passengers alongside his other goods, earning a reputation as a savvy young businessman.

His world changed dramatically one day at a train station. He saved the three-year-old son of a station agent from being hit by a runaway train. As a reward, the boy's grateful father taught Edison how to use the telegraph. This was his first deep dive into the world of electrical technology. He became fascinated with the system of dots and dashes and quickly became a skilled telegraph operator. This job took him across the country, allowing him to tinker, learn, and see firsthand how technology was changing the world.
