About Edison's later years

It will be a priceless treasure if those who make unremitting efforts can leave their fanatical spirit to their descendants at the end of their lives. life

It's too short, there are so many things, can you go forward without suffering?

Thomas Alva Edison

In his later years, Edison was still nervously carrying out his invention and creation activities, just like when he was young. One of them is about

The "invention" in Edison's Test Paper 1928, he successfully extracted rubber from weeds. At the age of 80, he was still insisting.

Working hard, he made up his mind: "As long as I can live, I will work."

The Invention of "Edison Test"

Edison's personal characteristics in his later years are: his speech is still mixed with the intimacy and simplicity that he had in his youth.

Square stress; The epigram he said is profound and just right, and most people can understand it. He is interested in hard work,

Moderation and unpretentious praise resonated throughout the United States. After the war, he became a famous figure in America.

1918 65438+1On October 24th, the Edison Pioneer Society, founded by several colleagues of Edison, was enough to express the love of the whole country.

Sheng Di's deep admiration.

When Edison was old, he often used his spare time to travel, mostly in summer, as a two-week camping trip. such

Travel often involves Henry Ford and Dr. john brown, natural history authorities, and sometimes even Warren Harding.

The system will also add fun. 19 19 years, three people stayed together for another two weeks. They crossed the Smokey Mountains and came to the west.

Virginia, then Ashville, North Carolina, then Shenandoah Valley, and then Maryland. 19 19

In 2008, the original simple equipment was developed into a fleet of three cars, including a "kitchen car" with a lot of gasoline in it.

Stoves, special food cabinets and refrigerators. They drive to lakes and mountains, sleep on the ground and cook on the fire.

In the evening, they sit by the fire, tell stories and talk about their lives.

19 19 After the war, they planned a bigger trip. At the same time, they also hope to be heavier during the trip.

Carry forward the spirit of the first brigade returning to the jungle. But in fact, such a possibility no longer exists. If you say, Fu

Robert has become famous all over the world, so Edison has become a mythical figure. Some weirdos may ask, "Who is Edison?"

A typical example is that Edison met a little girl in a remote village. When Edison asked her if she knew him

When he called, she replied, "You are Mr. Phonograph."

They traveled again at 192 1. Not only the wives joined them, but also their sons and daughters-in-law. Faye Si Tong is here again.

His old friend President Harding and his wife were invited, and they were invited to spend the night with everyone in the camp. See the president in a week.

The day came, with a secretary, six security guards, nine photographers and 10 Washington reporters. At the initiative of the president.

Next, a bishop and his wife were invited. In this way, they set up 20 tents and became a vast tour group.

1924, their last trip. Faye Si Tong complained, "Damn, this is hardly a trip."

Into a traveling circus. Ford's adjutant Charles Sorensen said, "Groups of journalists and rows of photographers.

Write reports and take photos for the collection of biological specimens by these four celebrities. This quiet outing turned into a beautiful trip.

The first performance at the pier. Of course, Ford likes publicity. "

Apart from spending a little time traveling, Edison still worked hard. He is over seventy years old, and people advised him to reduce his work.

After measurement, I still work 16 hours every day. He also firmly controlled the record player industry and other industries in West Orange. Sometimes, mining

Visitors will rashly ask him when he plans to retire. Edison's answer has two ways. One is "before the funeral", and secondly,

Yes: "when the doctor brought the oxygen bottle." When someone asked him how he planned to spend his old age, he said unhappily:

"You shouldn't think of these. I am quite energetic now, so I will continue to work hard. "

He not only said so, but also did so. In his later years, he still maintained the spirit of an inventor. On one occasion, Edison

He said, "It seems that the recent school education is to cultivate a certain form of people, and people's wisdom has not been fully developed. In fact, only

There is no need for the teacher to teach you what you can know by reading. It is better to cultivate teenagers' own thinking ability.

Force, otherwise there is no hope of great development in the future. "

"I agree with you." It was Ford who repeated the sound. "Mr. Edison, what kind of education do you think you need?"

"In my institute, many young people want to work every year. I put forward all kinds of questions to test them, many of which were mixed.

Ming has nothing to do with industry. Some young candidates seem to disapprove and think that my question is beyond the scope.

I don't need a young man like that. The purpose of asking a lot of digressions is to see if the young man is mentally sound.

Do you have the personality to work in my institute? "

"It's really good!"

"Mr. Ford, I often think that the United States will have greater development in the future, and we need to train excellent successors.

Only. There must be many outstanding young people in America, but is there any way to find these outstanding young people? If we can find this,

Excellent young people, I want to offer scholarships to study in universities. "

The exam will be put into practice immediately. The jury consists of Henry Ford, the great photographer george eastman and MIT.

Dr. Strandt, Dean, Lin Bai, a transatlantic flight adventurer, and Berry, another dean of the college, are composed of five people.

The first exam, the way is to choose an outstanding young man from each state, plus 49 representatives from Europe, to gather Edison.

Take the final exam at the college.

A total of 57 questions are divided into four categories: the first category is physics, the second category is chemistry, the third category is mathematics, and the fourth category is routine.

Knowledge. One to three questions are given by specialized scholars, only the fourth category. As a member of society, it depends on his contribution to society.

Method, so the special use of Edison's opinion. For example, physics has the following questions: "Talk about noise and music, sound."

The difference between rings. ""The organ in the church, if there is no heating equipment, will change its tune every time it meets cold weather. This is for the sake of

What? "

After the exam, the questions were published in major American newspapers. Everyone wants to test their abilities, so once the report is answered,

They are all very interested. The famous Dr. Albert Einstein said after reading the chemistry test, "This is too difficult.

Even if I pass the exam, I'm afraid I won't pass it. "This sentence was immediately published in the newspaper, and the readers all laughed.

Edison's fourth kind of problems are all unexpected, and most people are interested in them, such as (1) if.

You inherited a million dollars. What are you going to do with it? (2) Which of the following topics would you like to work on? Happiness, happiness and elegance

Theory, fame, money, love. (3) When you look back on your life before you die, what determines the success or failure of your life?

Defeated (4) When do you think you can lie?

Indeed, such questions as those raised by Edison can be said to be major events in life. The highest score in the exam is 92 points.

It turned out to be a boy of 16 years old, except for three teenagers who passed. Edison gave these four teenagers four years' education.

Study scholarship.

Edison's work has a characteristic, that is, if he does it, he will not only do it, but also work hard. "When I call my hand.

When a servant does something, I always ask him to do it at once. Of course, it is good to look at the test records in advance before starting work.

Yes, but things have to be put off until tomorrow; I want to make a decision now. It's not convenient for me to waste time, and besides,

Actually, it's not convenient for the whole part ... "..." If one of my employees

When I can finish half or more of my scheduled work, I will observe him for a long time until I find him.

Here comes the reason. I think it is shameful for students in ordinary schools to get only 60 points. "

Edison also designed test questions for people who applied to work in his company. The exam questions are mixed. test paper

A total of 150 questions, these questions have a feature, that is, they have nothing to do with the work content. Because there is no connection between many problems.

Edison was sharply criticized for this. The reporter of Scientific American interviewed Edison continuously.

Then I published a long article. Edison's explanation is that managers hired in other ways are difficult to be competent except for exams.

In Edison's view, the most important quality of being a manager is memory. But he also thinks: "It's not that you have a good memory."

People must be good managers. Maybe some people have excellent memories, but they can't bear the heavy responsibility of bargaining. But, if his

A good memory has one basic condition, and other conditions are secondary. "

192 1 year1month Scientific American said, "Edison thought that if you want to test whether a person can work.

Dry method is too wasteful. He lost 5000 yuan because of his subordinates' forgetfulness. "

Most of Edison's tests are common sense. For those questions involving technical data and chemical equations, just read.

Anyone who has read the textbook can answer. Some problems are math games. Some questions are about the author of an article and a fact.

Discover people. Other issues need to be judged.

Through investigation, Edison came to two conclusions: First, people's education level is far from their professional requirements. Zaishou

Of the 7 18 candidates in this exam, only 57 scored 70 points. Later, it was reduced to 40, which was considered as "medium"

Wait a minute. "Only about 32 80 points. The second conclusion is that this kind of exam is really effective. The people he hired got good grades.

Some people will become excellent managers in the future, and those who fail the exam are not qualified for the position of manager. Edison said that he

Our grades are the worst (XYz). So, as far as Edison himself is concerned, he made a positive conclusion about the exam.

Looking for a new chemical material-rubber

Edison used to explain the prospect and significance of his latest invention to people, but now he has been trying to cope with it.

Problems related to the world and human beings, like previous technological inventions, have long been foreseen.

1922, he foresaw atomic energy far better than most people, even most scientists. Edison is there.

I wrote in my diary: "Atomic energy will be discovered one day. In fact, I have been growing up in my own laboratory.

In terms of atomic energy, there is no hope to make more predictions at present. "

At 74, Edison was still interested in "everything" and full of optimism. He began to study ether again. Eddie

The student said, "This study is for entertainment. Now, I just look at the relevant literature and understand other people's thoughts.

Information published by others and their findings. At present, I can't judge whether the conclusion about ether is correct. If love

Einstein can make new discoveries in space, time and geometry, which explains people's understanding of ether now.

The knowledge is not finished. But at present, I can't express any opinions because I don't have enough data at hand. No data.

I mean, all the data. I can't work. "

When The New York Times reporter asked him to comment on the economic situation in the United States, he did not hesitate to say that the economic situation in the United States is

There's something wrong. But "as long as you have perseverance, determination and hard work, you can get it on the right track ... don't."

Call it panic. This is just a depression, there is no need to worry, as long as we are determined to overcome the difficulties. "Although

However, people pay attention to his opinions, but his "new currency" plan has been criticized by experts as surpassing silver without thinking.

Give up the practical possibility of line management.

Although Edison won a high honor, he still received visiting reporters as before, or strictly.

I kept my work habit in West Orange. He has breakfast at 8 o'clock every day, half a glass of wine, a cup of coffee and a piece of baked noodles.

Bag. After breakfast, he drove to the laboratory, read a report written by a project leader, and then disposed of his hands.

Chief research work, generally have to stay up late to go home, it is rare to drive back before dark. Edison often, too.

He went to new york and Chicago on business, but he still tried to avoid formal banquets as in his early years. Because of deafness,

He can't hear other people's speeches. Besides, he hates appearing in public in elegant clothes.

On the issue of diet and health, he still goes his own way, even if he is in poor health, he has to be repeatedly questioned by others.

Advise to see a doctor. When the doctor advised him to strictly control his diet, he found out his own diet rules, and he elaborated

After analyzing the effects of various foods on the body, I cut off all the meals that may cause trouble to the body and declared myself self-sufficient.

Milk drinking therapy will be adopted. 8 1 year-old, suffering from pneumonia, insisting on walking treatment, refusing to take medicine, stubborn personality.

I firmly believe that sleep will also cure his discomfort.

Edison came to Florida when he was 8 1 year old. On his birthday, new york's friends held a party at Astor Hotel.

Feast, but he himself can't attend. He sent a telegram from Fort Myers: He is working happily at the moment.

At the banquet, Meadow Croft stood up and reported Edison's "work":

"Because of the thoroughness of his talent, he is now exploring all the knowledge about rubber planting and manufacturing. Other ginseng

He has taken an examination of countless materials, not to mention newspapers and magazines on this issue at home and abroad. He has read enough books to fill in.

Two 5-foot bookcases.

"His purpose is to produce grapes from the southern States of the United States and other States that are cold to MINUS 20 degrees in winter.

Rubber is extracted from vines, shrubs and miscellaneous flowers. "Mr Edison has been doing this great and hard work; but

He is very satisfied with this job, and he still deals with this problem with his thorough spirit, abundant vitality and infinite enthusiasm.

Title. I have never seen him so absorbed in his life's research work as this time. He told me a few months ago.

I have studied physics for 60 years, and now I am engaged in some completely different subjects, so,

I feel very happy. Now he is really at the peak of his work in Florida. This time he took it to the lab.

Seven assistants are inside. Before he left, he had collected and tested 945 kinds of plants, and he found that many kinds of plants contained

With good quality rubber, now he will try more plants, maybe twice as many, maybe more. "

Edison was very interested in the possible problems in growing rubber in America. This is a whole for Edison.

New occupation. 10 years ago, that is, 19 15 years ago, when he visited burbank's nursery in Santa Barbara, he discussed holidays with Ford.

If the United States participates in the European War, how should the rubber supply be solved?

After the war, Ford expanded the Ford Motor Factory in Detroit and invited Edison to visit it. Ford at that time

He said to Edison, "all the equipment for making cars can be produced in the United States, only rubber needs to be imported." From now on, car number one

It is just around the corner to replace American feet every day, but the rubber used to make tires has to be imported from abroad.

No, this is really a big problem in America. "A few years later, Ford suggested that Edison set out to study this problem.

Edison accepted Ford's suggestion and established Edison Plant Research Company on 1927. Edison used Ford and Fei.

Si Tong invested $90,000 to buy a rubber plantation in Fort Myers and built a new laboratory. Although the war

Has stopped, but the threat of war has not been completely eliminated. Worried that the war will cause difficulties to the rubber supply in the United States, Eddie.

Students have a strong interest in rubber production. He wrote: "Don't think that there will never be another war, although we may."

There is no threat of war for a long time, but sooner or later European countries will unite to attack the United States. Then they

The first thing to do is to cut off our rubber supply. "

Edison thought, "Can't plants other than rubber trees produce things of the same nature?" The oak tree needs to cross there.

It takes several years to harvest rubber. If we can harvest the same thing every year like weeds, it will be easy. "He recognized.

Therefore, plants in North America and South America should be collected first, and tree sap should be taken in turn for research.

Therefore, he sent botanists from Fort Myers to look for plants that can extract latex all over the world. In order to satisfy

The urgent demand for rubber in the United States requires that the growth period of plants collected must be very short. "It will mature in eight or nine months, and it is indeed true."

Plants harvested by machines to provide rubber. The process of taking glue will also be mechanized, and manual work will be used as little as possible. "

It is not easy to meet such requirements. At this time, all the Edison family wanted was rubber. In the words of Mrs Edison

"Our family has been talking about rubber," he said. What we say, think and dream are erasers. Because besides that,

Besides, Mr Edison forbade us to do anything else. Although Edison wanted to lock up his family until they found out.

The solution was released again, but the idea was difficult to realize.

In less than a year, people sent people around the world to look for plants to extract latex, collected about 3000 kinds of plants, and then returned to the United States.

Country. After analyzing 14000 plants, Edison thought that several compositae plants might meet the requirements. Through miscellaneous items

In fact, Edison cultivated a plant with a height of 12 feet and a lot of latex. He gave this plant to Faye Si Tong I.

In batch, Firth made four tires of Ford station wagon from the rubber extracted from it. However, using this compositae plant

The cost of extracting glue is too high. Edison has rich experience in how to reduce costs. He concluded that the future cost can be reduced to

Competition level with imported rubber. 1928, the old inventor continued to experiment hard. He said, "Give me five more years.

Time, I will definitely let the United States have plants that often produce gum every year! "He estimated that he invented the economic extraction machine of chrysanthemum per mu.

100lb of rubber can be made from home plants. "I hope the output can be increased to 100 days, 10 pounds, and we are still driving.

At the beginning, the working principle was determined, and the hope for the future was really endless. "Edison suffered from renal insufficiency syndrome.

Sick, they had to give up the planting research of rubber plants. When Edison's successor took over the task, it was already

No longer extracted from compositae plants, but synthetic rubber. Edison's achievements in extracting rubber from weeds are highly praised by the world.

Evaluation.

Eternal glory

1929101October 2 1 day is the 50th anniversary of the birth of electric light. The Ministry of Posts and Telecommunications specially developed raw carbon fibers.

The commemorative stamp of the electric light says "Edison's first lamp". Henry Ford put Edison's building in Monroe Park.

Things, rebuilt in dearborn, Michigan. Church-like long laboratories, gorgeous offices and low brick house machines.

Factories, glass blowing rooms, charcoal burning sheds, trees and red clay have all been removed, and everything is the same as in Monroe Park.

The scene is the same. These rooms are well decorated, waiting for the owner who worked here 50 years ago to revisit his old place.

Edison was particularly excited when he walked into the laboratory where the replica was on display. His laboratory stands in front of us, surrounded by white.

The colored fence is exactly the same as that erected in Menlo Park Laboratory 50 years ago, so it is difficult to tell the truth from the false. Spread on the ground

The soil on the surface was also pulled by several trucks from Monroe Park. Edison sighed after reading it: "This is really cute in New Jersey."

Clay. "

Edison walked into the model and went to the second floor of the experiment, followed by Ford and Edison in Monroe Park.

Several colleagues. Among them, Francis Gill was in Europe before, and people from Ford Company found him and invited him to go boating together.

Atlantic, ask him to play a role in this exhibition. A reporter from Detroit Freedom wrote: "When Edison left,

When he sat down in front of a chair, everyone around him stood still, more than ten feet away from him. Everyone is silent, tourist.

The children seem to be unanimously aware of the seriousness of this situation; I realized that memories of the 82-year-old man in front of me flooded in.

The scene unfolded before us. He sat there without saying a word, his hands crossed, revealing an indescribable loneliness. this

Is a lonely genius, he lived longer than his contemporaries, and no colleague in this world can share this time with him.

The realm, thoughts and feelings of this place.

"For about five minutes, or perhaps within 10 minutes, this situation was not affected by any movement or action.

Excuse me. Only Edison looked around from time to time with tears in his eyes. Later, he cleared his throat and broke it.

The silence of the "laboratory" "

Ford spent a lot of time on the details of this exhibition. When he tried to restore Eddie with fragments picked up from the garbage

When Sheng showed Edison his old bowls, Edison said that the whole building and its interior furnishings were accurate to 9/ 10. Ford

I felt quite uncomfortable after listening to it. I asked what happened. Edison replied, "Our floor was never like this at that time."

Clean. "

2 1 the weather turned from sunny to dark in the morning, and the special car of President Hoover and his wife from Washington was also at this time.

Here we are. Edison and his wife went to meet him, and they took the19th century wood fuel train to Ford Calendar.

History museum. During a short trip, Edison relived his childhood. He took a conductor's basket.

The son shouted "candy, newspaper" to his peers in a weak voice.

After the president helped Edison get off the bus, they visited the Ford History Museum. In the evening, everyone is arranged to "experiment"

Room ",watch the prepared performance. When the guests walked into the "laboratory" in the dim light, there were millions in America.

The audience has already stood by the radio, waiting to hear the live explanation from the live announcer, because Edison will hold a show here.

He gave a dramatic performance about the electric light experiment half a century ago, but the model was slightly inferior to that of that year.

Francis gill has a vacuum pump ready. Edison sat by the pump and ordered, "Let's go, Francis." one

Later, the pressure was getting bigger and bigger, and Edison got up and turned on the power. The electric light began to shine, getting brighter and brighter until it was as bright as white.

Day. At the same time, all the lights nearby swished on. Similarly, dozens of cities across the United States also commemorate Eddie.

The achievement of life makes all the light shine.

In the room, rectangular dining tables are arranged in a zigzag pattern. The farthest end is the chairman's seat, and the honor seat in the middle is reserved.

The president and his wife sat down, but the president and his wife insisted that Edison and his wife sit down first. At the banquet, President Hoover delivered a speech: "In

In our country, scientists and inventors are the most valuable and priceless treasures. With their creativity and piety.

Gradually turn your scientific ideas into facts for everyone to enjoy. Thanks to their efforts, we have made progress.

Step, this great contribution is priceless.

"Mr. Edison jumped from an ordinary beginning to a great man in the world with his genius creation. His life

Gave us new confidence. We believe that people of our time will be able to support opening the door of opportunity and realizing their wishes.

People who want to go in go in.

"Human civilization is like a garden, and its quality is determined by the quality of flowers. We spent a lot of money on cultivation.

Less energy makes it fertile, and we can harvest as many flowers as possible to resist destructive forces.

Flowers; And because of the fragrance of these lives, we are encouraged to make new efforts and give us new strength and strengthening.

Our faith in the future. "

There is no greater gathering to pay tribute to an ordinary citizen. All kinds of people-finance

Economists, politicians, scientists, industrial giants, railway station owners, university presidents, artists and playwrights-all come to welcome.

He, they spent the whole day sightseeing in this historic village. In the evening, everyone walked into a house similar to an independent hall.

In the middle is a huge brick house with the inventor's autograph on the cornerstone in the middle.

There are 500 guests coming to the banquet, most of whom are figures in the world celebrity dictionary. From the Atlantic Ocean

Madame Curie, the inventor of radium, came from the other side of the Pacific Ocean, a senior engineer in Japan and

Official representative. In addition, there is Orville Wright, the pioneer of aviation; Banker Otto

H. Kahn); Webmaster Daniel Willard; JaneAddams of Hull Building in Chicago is very small.

Sister; Film mogul Will Hayes; Philanthropist Rosenwald; electrical engineering

Grandson of teacher Alexander (son of Dr. E.F. Alexander); Former Ambassador to Turkey Morgan Tao

(HenryMorgenthan); Humor master wil rogersl; Steel manufacturer Xu Wabo (Charles

Schwab); James Gerard, former ambassador to Germany; General Electric Company Manager swope

(GerardSwope); Adolf s, publisher of The New York Times. Ochs); President of the American Federation of Trade Unions

William C. Green and others. That night, the British prince and German President von Hindenberg.

All sent congratulatory messages. Richard e bird, the expedition leader who was present at the time, also sent congratulations.

In the ice and snow of the American base in Antarctica. At the same time, the phone call from Germany also carried Albert Einstein's wishes.

Sound.

Edison made a few short remarks at the banquet. At the end of his speech, he paid tribute to Henry Ford. Edison said, "I only

I can tell you in the most complete and appropriate sentence-he is my friend. Good night, everyone. "This invention is very big.

Wang, perhaps excited and tired at the same time, suddenly changed his face, and the onlookers immediately called Herbert Hoff.

The president's doctor gave him a shot in the arm. Everyone helped Edison to the next room and had a rest. He gradually got better.

Edison's health went from bad to worse after his trip to dearborn. Now, he goes to the factory less often and works less hours.

It is shorter than before. The place where he works is not the original laboratory, but a room in Glenmont. He spends every afternoon.

The driving distance is not as long as before, and the control of factory affairs is gradually transferred to his assistant. from

From 1930 to 193 1, he insisted on making decisions for the company as much as possible, which shows that Edison's spirit was not wavering.

There is nothing left.

In June, the United States was in the Great Depression. When Edison learned that there was an electric light convention in Atlantic City,

I was holding a telegram full of enthusiasm. In his telegram, he said to the delegates at the electric light conference, "What I want to say to you.

Be brave. It took me a long time to see that history is repeating itself-many depressions in industry and commerce. But every time

After the Great Depression, America became stronger and more prosperous. You must be as brave as your parents. Attic faith

-go forward bravely. "

This may be Edison's last telegram. In July, he arrived at the rubber cultivation test site in California. Past cultivation

This rubber plant is only one meter high. The amount of rubber collected is also very small, but it can grow to 3 meters after research and improvement.

Tall man. "In another five years, the rubber needed by the United States will not need to be imported from abroad." Edison told his colleagues who worked in the proving ground.

So.

1 in August, Edison was seriously ill, and the doctor diagnosed him with various symptoms of Brett's disease, uremia and diabetes.

It is estimated that he won't last for a few days, but the doctor announced that he would take care of the public mood: "Mr. Edison can compare."

A ship that sails only in narrow waterways. He may get through it safely. Or touch rocks. "But this statement did not make the people of the whole country

Rest assured. Surprisingly, Edison's danger passed quickly, and there was no need to make an announcement every day. A few days passed.

Son, his habit of driving for a walk every afternoon has also returned.

At the beginning of September, Edison's illness entered a critical period again, but he survived again. When he asked the doctor about the medicine prescribed

When things will play any role, they are just disappointed that they have not recovered quickly. 10 year 10 4, the doctor concluded that his illness was incurable.

Saved it. People from all over the world visit him every day. The Pope sent two telegrams asking about his health. President hoover

Pay attention to telling Edison's illness by phone every day. A large number of letters and telegrams of sympathy poured into the room. fort myers

The Chamber of Commerce decided to take Sunday, October 4th, 65438/KLOC-0 as a day to pray for Edison's recovery.

Nine days passed without any liquid. 120 hours, I only drank 6 teaspoons of pear juice. Edison fell into

Coma. Before that, he looked into the valley through the bedroom window, where he was playing with the children at the beginning of the world.

This place. At that time, he smiled and said, "It's really beautiful there." Prior to this, he also met with Faye Si Tong, who won the victory.

He smiled and pointed out to Fei Si Tong that there were four tire samples made of rubber extracted from Compositae plants in the house.

193 1 year1October 18, at 3: 24 am on Sunday, the great inventor Edison was already a great man in 84 years.

The journey of life.

On his deathbed, he said, "I have done my best for the happiness of mankind, and there is nothing to regret!" " "

Three days later, on the evening of June 65438 +2654381October +0, the body of this great inventor was buried in the university near his home in West Orange Creek.

Under the oak tree

As soon as the news came out, people fell into great sorrow. News of condolences rained down from all over the United States and other countries around the world.

At the same time, Edison's family and the White House also received thousands of suggestions on how to commemorate Edison.

Emile Ludwig, a German biographer who praised Edison more than once, argued that after the commemoration began, the whole world

All the lights were symbolically turned off for one minute. Some people argue that President Hoover ordered the power supply to be cut off throughout the United States on the day of the funeral.

Take a break for a minute. When people find this idea impractical, some people suggest everything except the key light.

The lights are automatically turned off.

At that time, all parts of America went out.
