Thomas Edison

Before the laboratories, the patents, and the nickname “The Wizard of Menlo Park,” Thomas Alva Edison was a curious boy in Michigan with little formal schooling and a habit of learning by doing. Born on February 11, 1847, in Milan, Ohio, he grew up in Port Huron, Michigan, after his family moved there in 1854. His mother, Nancy, a former school teacher, taught him reading, writing, and arithmetic. Most of the rest he found in books and experiments, especially after a book on natural and experimental philosophy stirred his interest in electricity.

Edison’s childhood also shaped the way he worked. He developed serious hearing problems at age 12 and was later completely deaf in one ear and barely hearing in the other. As an adult, he believed the loss helped him shut out distraction and concentrate. He began earning money young, selling newspapers, candy, and vegetables on trains between Port Huron and Detroit, and used much of his profit to buy equipment for electrical and chemical experiments. He even founded the Grand Trunk Herald, a small paper sold with his other papers, proud enough of it to keep the first issue framed in his home for the rest of his life.

At 15, after saving a child from a runaway train, Edison was trained by the grateful father as a telegraph operator. Telegraphy became his first proving ground. From 1863 to 1869 he worked night-shift jobs in Ontario, Michigan, Kentucky, Ohio, and Massachusetts, studying, tinkering, and building a reputation among other operators as bright and experimental. Sometimes that tinkering interfered with his work. In Boston he made money on a stock ticker, then lost it trying to expand in New York. His first patent, granted on June 1, 1869, was for an electric vote recorder. By 22, he had sold early inventions and moved to New York to focus on engineering.

Investment, publicity, and relentless work turned Edison from a restless telegrapher into one of the most productive inventors and businessmen in American history. By 29, he owned a telegraph recorder factory in Newark with more than one hundred employees. He then developed Menlo Park, now considered the first industrial research laboratory, where he drove himself and his staff to exhaustion. Over his lifetime, Edison registered 1,093 patents. His invention of the phonograph brought him international fame, though it took many years to become a commercial success. Later, at West Orange, New Jersey, he built an even larger research lab.

In 1878, Edison began work on an electrical lighting system meant to replace gas lamps. The path from light bulb to modern electric grid took decades of invention, investment, and influence, as Edison and his colleagues helped build systems of bulbs, generators, and electric distribution. Competition with Westinghouse’s AC system forced Edison to yield and led to the creation of General Electric. Even then, illumination never held all his attention. He ran a mining company that was never profitable and nearly ruined him, later started a cement company, and worked on a motion picture camera that grew into the first movie production studio. His companies also produced batteries, movies, musical records, and phenol, and his last obsession was domestic rubber production.

Edison’s private life was less orderly than his public image of tireless invention. He had three children with his first wife, Mary, but was neglectful; she died at 29, and his relationships with his children remained troubled. He later married Mina, had three more children, and in adulthood began to take more interest in his sons, who eventually worked for him. He faced health problems from experiments with toxic and radioactive chemicals, as well as a lifelong battle with diabetes, yet kept working vigorously until his death on October 18, 1931. His words still fit the life behind them: practical, stubborn, and built around effort. “You only fail when you stop trying” sounds less like a slogan than a description of how he lived.
