Thomas Alva Edison

is one of America’s most famous inventors. saw huge change take place in his lifetime. He was responsible for making many of those changes occur. His inventions created and contributed to modern night lights, movies, telephones, records and CDs. was truly a genius.

is most famous for his development of the first electric light bulb. When was born, electricity had not been developed. By the time he died, entire cities were lit by electricity. Much of the credit for electricity goes to .

Some of his inventions were improvements on other inventions, like the telephone. Some of his inventions he deliberately tried to invent, like the light bulb and the movie projector. But some inventions he stumbled upon, like the phonograph. Of all his inventions, was most proud of the phonograph.

invented and improved upon things that transformed our world. Some things he invented by himself. Some things he invented with other people. Just about all his inventions are things we still use in some form today. Throughout his life, tried to invent things that everyone could use.

created the world’s first “invention factory”. He and his partners invented, built and shipped the product - all in the same complex. This was a new way to do business. Today many businesses have copied ’s invention factory design.

A business friend once asked about the secret to his success. replied, “Genius is hard work, stick-to-itiveness, and common sense”. But his “common sense” was very uncommon. More patents were issued to than have been issued to any other single person in U.S. history: 1,093.

Early Life

was born February 11, 1847 in Milan, Ohio. He was the seventh and last child of Samuel , Jr. and Nancy Elliot . His parents had no special mechanical background. His mother was a former schoolteacher; his father was a jack-of-all-trades - from running a grocery store to real-estate. When was seven years old, his family moved to Port Huron, Michigan. He was a very curious child who asked a lot of questions.

The Education of

began school in Port Huron, Michigan when he was seven. His teacher, the Reverend G. B. Engle considered to be a dull student. especially did not like math. And he asked too many questions. The story goes that the teacher whipped students who asked questions. After three months of school, the teacher called , “addled,” which means confused or mixed up. stormed home.

The next day, Nancy brought back to school to talk with Reverend Engle. The teacher told his mother that couldn’t learn. Nancy also became angry at the teacher’s strict ways. She took out of school and decided to home-school him. It appears he briefly attended two more schools. However, his school attendance was not very good. So nearly all his childhood learning took place at home.

Loved to Read

’s parents loved to read. They read to him works of good literature and history. They had many books that young Tom eagerly devoured. Before he was 12, he had read works by Dickens and Shakespeare, Edward Gibbon’s Fall of the Roman Empire and Decline, and more.

Nancy encouraged her curious son to learn things for himself. His parents were dedicated to teaching their children. They did not force him to learn about things he didn’t enjoy. So he learned about things that interested him the most.

When was nine Nancy gave him an elementary science book. It explained how to do chemistry experiments at home. did every experiment in the book. Then Nancy gave him more books on science. He soon loved chemistry and spent all his spare money buying chemicals from a local pharmacy. He collected bottles, wires, and other items for experiments.

At age 10, built his first science laboratory in the basement of the family’s home. His father disapproved of all the time spent in the basement. Sometimes Sam offered a penny to if he would go back to reading books. But often used his pennies to buy more chemicals for experiments. He labeled all his bottles “Poison”.

First Job

When was 12 years old, he took a job as a train boy on the Grand Trunk Railway. The train traveled from Port Huron, to Detroit, and back to Port Huron, all in one day. sold newspapers and candy to passengers. He also printed a weekly newspaper, the Weekly Herald. He spent all he earned on books and equipment for his chemical laboratory.

After about a year, he got permission to move his home science laboratory to the train baggage car. He did his science experiments during the five-hour layover in Detroit. But one day the train lurched, spilled chemicals, and the lab caught fire. The train conductor threw and his chemicals off the train. His next job was selling newspapers at stations along the railroad.

Ear Problems

had many ear problems throughout his childhood. When he was 15, a train accident injured his ears more. When he tried to jump on a moving train, a conductor grabbed the boy’s ears to help pull him up. said he felt something snap inside his head. He soon began to lose much of his hearing. His deafness could have been cured by an operation. But refused the operation. He said being deaf helped him concentrate.

“Deafness probably drove me to reading,” he said later in life. He was one of the first people to use the Detroit Free Library. His library card was number 33. He went through shelf by shelf, reading every book.

enjoyed science books best of all. He devoured books on electricity, mechanics, chemical analysis, manufacturing, technology and more. He realized his future would be in finding ways to make our lives better, instead of just learning how something works.

The Fluxus Indians

There is a “tall tale” about how when was a young teenager he discovered some odd, discarded “Indian artifacts” and writings in a box at a public library in Port Huron, Michigan. From these records reportedly learned that a very creative Indian tribe called the “Fluxus” once lived in North America. The story goes that the Fluxus tribe had a long list of ideas for future inventions such as an electric light bulb, the office duplicating machine, the record player, the movie camera and projector, and even television. This story is entirely fictitious as the Fluxus Indians never existed. it is a “tall tale” something like the Legend of Paul Bunyan or Garrison Keillor’s “Lake Wobegon” –fiction presented as nonfiction.

First Invention

Nine years before was born, Samuel F. B. Morse was famous for inventing the telegraph. The telegraph sent messages over wires using “Morse code”. In morse code, the alphabet and numbers are written in combinations of dots, dashes, and short and long sounds. By the time began doing experiments, telegraph lines went across the country. He wanted to learn how to be a telegrapher and send messages over telegraph wires.

While selling newspapers along the railroad, something happened that changed his life. saved the life of a station official’s child. The child fell onto the tracks of an oncoming train. The boy’s father thanked by teaching him how to use the telegraph. used scrap metal to build a telegraph set and practiced the Morse code.

When was 16, he moved to Toronto, Canada. He became a telegraph assistant. His job was to report to Toronto every hour by telegraph signal. thought this was a waste of time. He invented a gadget that sent a signal even if he was asleep. This was his first invention - the transmitter and receiver for the automatic telegraph. His boss found him asleep. was almost fired.

Other Jobs

moved back to the United States. In his later teens he worked as a roaming telegraph operator. He went from city to city in the eastern US.

He hung around railroad yards, newspaper offices, and machine shops. He worked in a jewelry shop and at telegraph offices. He worked with clockwork, printing equipment, and different telegraphy instruments. He studied and experimented with these tools during his spare time.

He became an expert on the telegraph. The more he learned about telegraphy, the more he wanted to learn. He took apart equipment and reassembled it until he understood how it worked. He experimented with ways to make it better.

He visited used bookstores for science books. He ordered chemistry books from London and Paris. He filled his rented rooms with chemicals and junk metal for his experiments. The story goes he spent all his money buying science things and books, and wouldn’t buy clothing. One winter he went without a winter coat.

First Invention that made Money

When was 21, he got a job in Boston as an expert night telegraph operator. Even though he worked nights, he slept little during the day. He was too busy experimenting with electrical currents. worked to improve a telegraph machine that would send many messages at the same time over the same wire. He borrowed money from a friend, and soon quit his job. Now he could spend all his time inventing!

The first invention that he tried to sell was an electric vote recorder. It made voting faster and more accurate. But no one wanted to buy it. Today it is used in many states to record votes of legislators.

He moved to New York City in the summer of 1869. He had no money. A friend let him sleep in a basement office below Wall street.

spent a lot of time studying the stock market ticker. That was the machine that gave information about stock market prices. It was a spin-off of the Morse telegraph device. Once, fixed a broken stock ticker so well that the owners hired him to build a better one. Within a year he made the Universal Stock Printer. sold the rights for the stock ticker. He thought he might get paid around $4,000 for it. He got $40,000!

With all this money, started a business in Newark, New Jersey. He built stock tickers and high-speed printing telegraphs. At this shop he improved on the typewriter. Until improved it, you could write faster than you could type!!

Menlo Park - 1876

was a poor financial manager. In his late 20’s, he began to have money problems. After six years at his workshop in Newark, New Jersey, asked his father to help build a new “invention factory”.

built his new science laboratory at the village of Menlo Park, NJ. Now he and his two business partners could devote their full attention to inventing. promised that he would build a small invention every ten days and a big invention every six months! He also said he would “take orders” for inventions.

They moved into the new building in March, 1876. His first invention was an improvement on the telephone. Before ’s improvement, people had to shout when they used the telephone.

The new lab had around 60 employees. It didn’t matter to what a person’s background was. If he thought someone had talent, that was enough.

achieved his greatest successes in this laboratory. Soon he had 40 different projects going at the same time. He applied for as many as 400 patents a year. His ideas and inventions ranged from the practical to the crazy. worked at Menlo Park for over 10 years.

Electric Light Company - 1876

became business partners with some of New York’s richest people, J.P. Morgan and the Vanderbilts. Together they formed the Electric Light Company. They made this company before electric light bulbs had been invented. Today this company is called “General Electric”.

Phonograph - 1877

The phonograph was ’s favorite invention. He invented the “talking machine” by accident while working on telegraphs and telephones. The first words he recorded were “Mary Had A Little Lamb”. He was 30 years old. received his first patent for the talking machine in 1878. The tinfoil phonograph was sold to the public from 1878 - 1880 at prices ranging from $10 to $200. His wax-cylinder machines didn’t go on the market until 1888 - 1889 as rentals.

called the tinfoil phonograph a “talking machine” and a “sound writing” machine. This was no improvement of existing technology. It was not something he planned to invent. This was something brand new and ’s most original invention. And it happened by accident. He was working on ways to record telegraph messages automatically. continued to work on cylinder and disk phonographs for the rest of his long life, even receiving patents on them well into the 1920’s - over 40 years later! It was his longest continuing interest.

Invention of Electric Light - 1879

Scientists had been working to invent electric light for many years. Back then people used candles and gaslights to light their homes. But gaslights were smelly and smoky. After two years in his new laboratory, boasted he would invent a safe, mild, and inexpensive electric light.

searched for the proper “filament” or wire, that would give good light when electricity flowed through it. He sent people to the jungles of the Amazon and forests of Japan in his search for a perfect filament material. He tested over 6,000 vegetable growths (baywood, boxwood, hickory, cedar, flax, bamboo) as filament material.

In 1879, after spending $40,000, and performing 1,200 experiments, he succeeded. He made a light bulb using carbonized filaments from cotton thread. Carbonized thread is ordinary cotton sewing thread that has been burned to an ash. The light bulb burned for two days. The electric light took the greatest amount of time and required the most complicated experiments of all his experiments.

At the laboratory an Menlo Park, scientists could turn on and off different lights. This was something very new for the world. His bulbs were first installed on the steamship “Columbia” and later in a New York City factory.

World’s First Power Station - 1882

invented a system where many lamps could get electricity all at the same time. He set up the world’s first “electric light-power station” in lower Manhattan. New York City was the first city in the world to have electric lights. The Electric Light Company sent electricity to houses and lamps.

The Effect - 1883

One of ’s engineers, William J. Hammer, made a discovery which later led to the electron tube. The electron tube led to the electric signal, which led to electronics. Electronics is a branch of science that is related to electricity. Without electronics we might not have radio, TV, CDs, computers, X-Ray machines or space travel. The discovery of electrons was patented as the “ effect” which is the basis of electronics.

The Wizard of Menlo Park

People called “The Wizard of Menlo Park”. was often able to see possibilities others missed because he was constantly learning. When he was 30 and 40 years old he read everything he could about the latest developments in photographic optics. This helped him in his inventions for movie cameras.

West Orange, NJ Laboratory

In 1887 built a bigger invention factory in West Orange, New Jersey. This Laboratory was 10 times larger than his first lab in Menlo Park. It is now a national monument. This Laboratory Unit had fourteen buildings. Six of these buildings were devoted to the “business of inventing.” The main building alone was the size of three football fields!! It had space for machine shops, glass-blowing operations, electrical testing rooms, chemical stockrooms, electrical power generation, and other functions.

At the Laboratory they made new products and improved old products. Over 5,000 people worked there. attempted to personally manage this large staff. The story goes that when a new employee once asked about lab rules, said, “there ain’t no rules around here! We’re tryin’ to accomplish somep’n.”

Every day toured this huge facility to see what was going on. But he spent most of his time doing paperwork instead of experiments. He did his paperwork in the library. The research library was an office and trophy room. received many, many awards throughout his life. In the center of his office, sat at a desk with three dozen pigeonholes, surrounded by over 10,000 books.

At West Orange, improved the phonograph using wax records. Now he could build phonographs to sell to the public.

Out of the West Orange laboratories came the motion picture camera and silent and sound movies. His factory improved the alkaline storage battery, the electric pen, the copy machine, the dictating machine. Other inventions and improvements included a cement mixer, the microphone, and a magnetic process to separate iron ore.

invented the concept of film reels for motion-picture cameras. He also connected a motion picture camera to a phonograph. Now he could put sound with motion pictures! In 1913, introduced the first talking moving pictures.

Before photocopying machines were invented, invented an electric “pen” which was really a puncturing device that rapidly punched holes in a sheet of waxed paper. A historian suggested this “pen” looked like a sewing machine.

There were silly moments in the lab also. Sometimes they tried mixing chemicals that seemed foolish - coffee, eggs, sugar, and milk. His lab held everything for experimenting - whalebone, tortoise shell, elephant hide, and even the hair of a person, a native Amazonian. It is rumored that one of ’s friends said the lab storeroom even had the eyeballs of a US senator!

Most of these lab substances had no practical use, but a few did. used rain-forest nuts to make phonograph needles. Japanese bamboo was used to make filament (wire) for his light bulb. The hair of the Amazon was used for a wig for the first talking doll. In the doll’s chest was hidden a tiny phonograph speaker.

In 1915, was appointed president of the U.S. Navy Consulting Board. He believed that electricity would make weapons more powerful. He claimed to have made an explosive that would explode if yelled at. He invented an electric torpedo. urged Congress to establish the Naval Research Laboratory in 1920. This was the first military research laboratory.

For more than forty years, the laboratory created by in West Orange, NJ, had enormous impact on the lives of millions of people around the world. ’s last patented invention was a way to make manmade rubber. The lab continued to invent things even after died in 1931.

It is Okay to Fail?

thought of disasters as learning opportunities. One time his lab stove went out in the dead of winter. Many expensive chemicals froze. Another time unprotected chemicals were damaged by sunlight. Instead of feeling sorry for himself, stopped all other projects and thought of ways to solve the problem. He learned to change the makeup of some of the chemicals.

Some historians believe learned his positive attitude from his energetic father. Sam was not afraid to take risks and he never gave up when a business project failed. Sam brushed himself off and started a new business. This positive message of persistence may have been why learned it’s okay to fail.

One challenge that failed at was the invention of an undersea telegraph. designed a laboratory model of a transatlantic cable. But the rumble of traffic outdoors shook the equipment so much they couldn’t complete the experiments. finally abandoned this project.

But what ruined ’s underwater telegraph experiments - noise vibrations and sound waves - is what made his telephone experiments work. He learned things from the undersea telegraph experiments that could help Alexander Graham Bell improve the telephone.

, the Man

married Mary Stilwell. was upset to discover that his new wife would not be his partner in his science laboratory. Just over a month after marrying Mary, the twenty-four-year-old wrote in a notebook, “My wife Dearly Beloved Cannot invent worth a Damn!!” In 1884, Mary died, leaving him with three young children. He married Mina Miller in 1886. He had three more children with Mina.

was five feet, 10 inches tall, gray eyes, long hair that looked as if he cut it himself. He wore baggy acid-stained pants and scruffy shoes. His hands were discolored by chemicals. Later he began wearing all black. Strangers mistook him for a priest.

was a workaholic. He could not tolerate laziness. He often worked as many as 112 hours a week. Both his wives complained that he spent all his time in the laboratory. He and his lab partners often worked late into the wee hours of the morning. Instead of going home to sleep, he took catnaps on a lab bench. His second wife, Mina, had a cot set up in a corner of his library so he didn’t have to sleep on a hard bench.

What makes different from other scientists, was his ability to take ideas and put them into practical results. was quoted as saying, “Genius is one percent inspiration and 99 percent perspiration.”

really had only one Eureka! moment. When he discovered the phonograph. Great ideas did not pop into ’s head like lightning bolts out of the blue. He was always looking for solutions to problems. simply loved the challenge of inventing. It was a test - to see how many possibilities he could come up with.

became very excited about any odd wonder. On his daily walk around the lab grounds, he discovered a bug giving an unusual odor. was so curious about this that he wrote to a famous scientist, Charles Darwin, about it.

As grew older, he became harder of hearing. But he never stopped learning. Typically he would rush into research, dashing off ideas and doing experiments as fast as they came to mind. Once the invention had been started, he left the details to others.

was known to be stubborn. When he was a senior citizen, he became protective of his inventions. One historian found an irate letter from to his manufacturing department. had learned that teenagers were turning up the speed of his cylinder phonograph to make the music faster. complained, “I don’t want it and won’t have it.” To make sure this would not happen again, he ordered his workers to make a control for the record speed.

died when he was 84 years old, on Sunday, October 18, 1931. He was still experimenting up until the time he died. Three days later, on October 21, 1931, electric lights were dimmed for one minute throughout the United States. and his wife, Mina, are buried on their home estate grounds.

is a folk hero. He is a legend. His inventions deeply effected the shaping of modern society. Some people say he single-handedly invented the 20th cenntury.

Good Businessman

was not the type of inventor we have seen on TV - hermit, genius, struggling alone in a garage or science lab. Teamwork was very important to his success. He surrounded himself with six or more assistants. Some were mechanics and some were electrical engineers. A person’s background didn’t matter, talent did. chose people he thought knew more about a subject than he did. ( did not think he was good at math.)

had a talent for motivating people and encouraging creativity. He encouraged everyone to write down ideas and diagrams. Good ideas were started by the experimenter in charge of the project. Then the group worked on it. It was impossible to give credit for an invention to any one person.

The brilliant scientist was also a clever businessman. wanted the streets of New York City torn up for the laying of electrical cables. So he invited the entire city council out to Menlo Park at dusk. The council members walked up a narrow staircase in the dark. As they stumbled in the dark, clapped his hands. The lights came on. There in the dining hall was a feast catered by New York’s best restaurant.

Another great accomplishment of was the invention of an entirely new way for businesses to work. and his partners invented, built and shipped the product - all in the same complex. This was a new and unusual way to do business at that time. Many modern businesses have copied ’s invention factory design.

Other Famous People Knew

Henry Ford worked at one of ’s laboratories. Henry later set up his own factory and made cars.

Harvey Firestone and Henry Ford asked to help them make better rubber for car tires. Together they tried growing rubber plants in Florida.

worked with George Eastman to make film strips. Eastman went on to be a partner in a company named Kodak.

Museums

’s Birthplace.The house in Milan, Ohio was restored in 1947.

Menlo Park. Around 1929, Henry Ford moved the Menlo Park laboratory to a huge museum in Dearborn, Michigan.

The Home. His home was called Glenmont. It was built in 1880 in the city of Llewellyn Park, NJ. It was ½ mile from the West Orange lab complex. The 29-room mansion contains the original items used by and Mina , their family, and their servants.

West Orange Laboratory. The Statue of Liberty and Ellis Island National Monuments, and Morristown National Historical Park are within twenty miles. In 1956 President Eisenhower made the research laboratory in West Orange, NJ, a national monument. In 1962 ’s home, Glenmont, and his West Orange lab complex were renamed the National Historic Site.

National Historic Site

saved everything. During the late 1950s and early 1960s, ’s business and ’s decedents donated his belongings to the National Historic Site. The museum collections show ’s sixty-year career as inventor, manufacturer, businessman and private citizen. All his inventions are here, including the first phonograph. The Site is about 15 miles west of New York City, N.Y. The address is: National Historic Site Main Street and Lakeside Avenue West Orange, NJ 07052

The size of the collection is shocking: 400,000 museum pieces! The writing documents (laboratory notebooks, sketches and working drawings) made by and his colleagues are around five million!!

You can also see a replica of the world’s first building used as a movie theater. called this motion picture studio the “Black Maria”, because it was made with black paper.

Papers Project

Everything invented was written down in excellent detail in 3,500 notebooks. These notebooks included laboratory records, early drafts of patent applications, letters, photos of models, and other memorabilia. A person could trace the invention process from the first thought of an idea jotted down in a notebook, through the experiments, and ending with a finished mass-produced product.

In 1978 eight historians wanted to look at all of ’s notebooks, sketches, and drawings. These historians were the first people to look at the documents since died. They were told there were over a million pages of documents. The historians thought it would take about 10 years to put the papers on microfilm and in a book. Their plan is known as the “ Papers Project”.

But the dusty stacks of papers were a mess. Many hadn’t been touched since ’s death. The historians went from building to building, room to room, drawer to drawer. It took more than a year just to find all the papers.

They found four to five million pages in the paper collection. The team has been working for 18 years. They are still working today. They are now in the process of putting ’s papers on computers. They might be done in another 10 years!!

wrote about many things in these notebooks. Between inventive thoughts, his mind drifted. Pages are decorated in different flowery styles of handwriting. He even wrote poems. He drew many sketches. In seems whatever he was thinking, he wrote it down.

In 1871, imagined that a flying machine could be built with wings. This was more than thirty years before the Wright brothers’ actually did it. ’s “flying machine” was never mentioned again. also wrote that the telephone was “perfected” one morning at 5 AM. But his quot;perfected” telephone, had many mistakes. Eventually, improved the transmitter portion.

Why was a Genius?

* believed in hard work and determination.
* Work habits. sometimes worked twenty hours a day.
* He was very good at bringing people together to make an inventing team.
* He was able to reason with many different people.
* He encouraged creativity in his employees.
* He knew a lot about what his competitors were working on.
* He almost never worked on any invention that wasn’t already being worked on by several other people.
* One of his biggest strengths - Perseverance. He never gave up. This idea is captured in his famous statement, “Invention is ninety-nine percent perspiration, and one percent inspiration.”
* Failure did not stop him. rarely got discouraged when experiments didn’t work out. A failed experiment shifted his thinking in different directions.
* He was able to solve problems and learn from failure.
* Attitude. He saw every failure as a success. The story goes that he failed 10,000 times in his storage battery experiments. But said, “Why, I have not failed. I’ve just found 10,000 ways that won’t work.”

was a home-schooled, self-educated person. He learned education was his own responsibility. He learned to be persistent. He learned reading was very important. He learned from watching others. He learned that science is fun. He learned that education is something that lasts your whole life.
