Thomas Edison Net Worth

Net Worth Information

What is Thomas Edison’s Net Worth?

Thomas Edison, the American inventor, author, and entrepreneur, had a net worth of $170 million at the time of his death on October 31st, 1931. However, it’s important to note that he experienced significant financial hardship throughout his life, and there were periods where his expenses on inventions outweighed his income from previous inventions. Despite this, Edison’s net worth has been adjusted for inflation to give a modern equivalent of $170 million.

Although Edison faced financial challenges, his contributions to technology and innovation were substantial. He held over 1,000 patents and invented the first commercially usable lighting system, the phonograph, and the moving picture camera.

Early Life

Thomas Alva Edison was born on February 11th, 1847, in Milan, Ohio. He later moved with his family to Port Huron, Michigan. His mother, a schoolteacher, played a significant role in his education and taught him fundamental skills such as reading, writing, and arithmetic. Edison developed an early interest in understanding the mechanisms behind various objects and often conducted experiments at home.

At the age of twelve, Edison suffered from hearing problems due to scarlet fever. However, he saw this as an advantage as it allowed him to focus better. During his adolescence, Edison displayed an entrepreneurial spirit and began selling various items, such as candy, newspapers, and vegetables on trains, making a significant profit at a young age. He also saved a child’s life, which led to him learning telegraphy and securing a job with Western Union in Boston.

In 1869, Edison moved to New York City, where he further pursued his inventing career.

Early Career

After initially facing financial difficulties in New York City, Edison secured a job with the Gold Indicator Company, where he fixed and engineered stock ticker machines. His salary at the time was $300 per month.

During this period, Edison obtained his second patent for an improved version of the stock ticker machine, which he sold to Western Union for $40,000. This invention proved to be successful, generating around $500,000 in sales and royalties for Edison.

Using the proceeds from his successful inventions, Edison established industrial research labs in New Jersey, including the well-known Menlo Park, Newark, and West Orange labs. These labs allowed Edison to continue his work and expand his inventions, with the West Orange lab becoming a sprawling facility occupying two city blocks.

One of Edison’s notable accomplishments during this time was the invention of the phonograph, which garnered widespread attention and earned him the nickname “Wizard of Menlo Park.” He obtained a patent for the phonograph in 1878 but made few improvements to the technology, with subsequent advancements primarily made by Alexander Graham Bell.

By the early 1900s, Edison’s company was generating significant revenue from phonograph sales, exceeding $20 million in the modern equivalent of $260 million.

Electric Light

In 1878, Edison began working on developing a practical electric light system to replace gas and oil lamps for indoor use. With the support of influential figures like J.P. Morgan and the Vanderbilt family, he formed the Edison Electric Light Company to pursue this venture. Although it is a common misconception that Edison invented the light bulb, it was actually invented by British scientist Warren de la Rue in 1840. However, previous versions of the light bulb were either inefficient or expensive.

Edison’s light bulb used a carbon filament, which allowed it to stay lit for over 1,200 hours. He conducted a public demonstration of his light bulb on December 31st, 1879. The first commercial use of Edison’s light bulb was in a steamship owned by The Oregon Railroad and Navigation Company. The Mahen Theatre in the Czech Republic became the first building to be outfitted with Edison’s lighting.

There was considerable litigation over various inventors’ patents relating to electric light systems, including Edison’s. Initially, his patent was ruled to be invalid and based on the work of William E. Sawyer. However, in 1889, a judge reversed the decision due to Edison’s improvements in the technology.

Other Work

Aside from his successful inventions like the light bulb and phonograph, Edison made significant contributions to other fields as well. He formed The Edison Illuminating Company, an electric utility company, and patented a system for the distribution of electricity. He also invented the fluoroscope, a medical device used for taking radiographs. Although Edison himself had little interest in X-rays due to fear, his design for the fluoroscope remains in use today.

In addition, Edison was granted a patent for the motion picture camera in 1891. While Edison is credited with the invention, his assistant at the time, William Kennedy Dickson, played a significant role in its development.

In the early 1920s, Edison established the Edison Portland Cement Company with $100,000 of his own money. The company was responsible for building the original Yankee Stadium.

Later in life, Edison attempted to produce rubber domestically, but the venture was ultimately unsuccessful.

Personal Life

In 1871, Edison married Mary Stillwell, who worked at his lab and was sixteen years old at the time. They had three children together. Unfortunately, Mary died in 1884 from a possible morphine overdose. Two years later, Edison married Mina Miller, who was twenty years old at the time, and they also had three children.

In 1886, Edison purchased a home in West Orange, New Jersey, for $125,000, where he resided for the remainder of his life.

Edison faced challenges with one of his children, Thomas Alva Edison Jr., who aspired to be an inventor but lacked the necessary skills. Edison took legal action to prevent his son from tarnishing the Edison brand, and an agreement was reached where Edison Jr. received a weekly allowance in exchange for refraining from fraudulent business practices. This allowance amounted to the modern equivalent of $1,019 per week.

Thomas Edison died on October 18th, 1931, due to complications from diabetes. He was buried behind his home in West Orange, New Jersey.

Net Worth Over Time

Thomas Edison’s net worth fluctuated throughout his life due to financial challenges stemming from the expenses of his inventions. At the time of his death in 1931, his net worth was estimated to be $12 million. Adjusted for inflation, this equates to $170 million in today’s terms. However, it’s important to note that if Edison had not been forced out of the Edison Electric Light Company and sold off his stake prior to its merger with General Electric, he would have potentially owned around $30 million worth of GE shares, which would be worth an equivalent of $500 million in modern times.

Components of Net Worth

Thomas Edison’s net worth primarily consisted of the income generated from his various inventions and patents. In addition to the financial gains from the sale and royalties of his inventions, Edison also had investments in different companies, including the Edison Electric Light Company and the Edison Portland Cement Company. However, it’s important to note that Edison faced financial hardships throughout his life and experienced periods where his income did not match his expenses.
