The following is the information I found about him:

1. Introduction

Benjamin Franklin (1706.1.17—1790.4.17) was an American industrialist, scientist, social activist, thinker and diplomat in the18th century. He is the first scientist and inventor in American history who enjoys an international reputation. In order to explore electricity, he once made a famous "kite experiment" and made remarkable achievements in electricity. In order to deeply explore the law of electricity movement, many special terms such as positive polarity electricity, negative polarity electricity, conductor, battery, charge and discharge have become world-wide vocabulary. He borrowed the positive and negative concepts in mathematics, and expressed the nature of charge scientifically with the concept of positive and negative electricity for the first time. And put forward the view that charge can neither be created nor destroyed, and later generations discovered the law of charge conservation on this basis. He first put forward the concept of lightning rod, and the lightning rod made of it avoided lightning disaster and broke superstition. He is an excellent politician and a veteran of the American War of Independence. He participated in the drafting of the Declaration of Independence and the American Constitution, and actively advocated the abolition of slavery, which was deeply respected by the American people. He is the first French ambassador to the United States, so he enjoys a high reputation in the world.

He was born in poverty. /kloc-dropped out of school at the age of 0/0 and went home to work. /kloc-since the age of 0/2, I have been an apprentice and helper in a printing factory. But he is diligent and studious. In addition to mastering printing technology, he also widely read works on literature, history and philosophy, taught himself mathematics and four foreign languages, and devoted himself to practicing writing. He often goes to the library of the printing house to read all kinds of books after a day's work. He didn't go home until his anxious mother came to the factory to look for him. All these laid a solid foundation for his achievements in many aspects in his life. In order to gain a foothold in the society at that time, he went through many twists and turns and founded his own business-printing house. Thanks to his efforts, reputation and management, he not only stood firm in the fierce competition in the printing industry, but also expanded his business to neighboring States and the West Indies. He became the leader of North American printing and publishing industry. He pays attention to observing natural phenomena and studying scientific problems. Starting from practice, he engaged in scientific experiments and observations, answered the question of "what is electricity" in electricity, called electricity in different states "positive electricity" and "negative electricity", put forward the "first theory" in electricity, and revealed the essence of lightning phenomenon in atmospheric electricity. Known as "the second Prometheus", these epoch-making electrical research achievements have made him a world-famous first-class scientist. He also has research in optics, heat, acoustics, mathematics, oceanography and botany. And there are a series of inventions, such as new stoves, lightning rods, electric wheels, three-wheeled clocks, bifocal glasses, automatic barbecue ovens, glass musical instruments, overhead book readers, new street lamps and so on. Therefore, it was awarded a master's degree or a doctor's degree by six or seven universities in the United States, such as Harvard University, Yale University, Oxford University, Edinburgh University and St. Andrews University. After becoming famous, Franklin did a lot of work in cultural exchange and social welfare in North American colonies. He has organized and established "* * * Reading Society", "American Philosophy Society", "North American Association for the Advancement of Science", newspapers, libraries, bookstores, hospitals, universities and fire departments. He also reformed the postal system in North American colonies and established a unified postal system in North American colonies. He was an outstanding social activist and became an influential figure in the North American colonies. He is not only good at solving special problems in natural science and practical problems in social and political activities, but also often explores many philosophical and social problems. He is a deist and believes that spirit is attached to matter. He believes that the reason of social poverty is that workers must feed parasites; He loves freedom and peace, opposes war, hates racial discrimination and slavery, and advocates safeguarding the interests of blacks and Indians. He was one of the most profound bourgeois liberal thinkers at that time. Franklin lived in the United States and was at a major turning point from a colony to an independent bourgeois country. He took an active part in the revolutionary movement. He made great contributions to the victory of the war of independence and the initial construction of the American national system. In 1754, at the Albany meeting attended by the leaders of North American colonies, he put forward the famous "Albany Alliance" plan, which was passed at the meeting, and became the first person to instill the idea of the grand alliance of the United States of America into the colonial people. In Pennsylvania, he always fought against the lawlessness of the owners' group with the colonial people. 1764, he went to London for the second time and asked the British king to protect the interests of the colony, but there was no result. Later, the British government strengthened its repression of the North American colonies, which inspired the colonial people to struggle more strongly. Franklin's position turned completely to revolution. Pennsylvania was originally a landlord colony, and 168 1 was awarded William Penn by British King charles ii. Later, william penn's two sons inherited the property. Owners have the privilege of appointing officials, including the governor, vetoing parliamentary bills, and being exempt from taxes in the colonies. 19438+0775 In May, he returned to the United States and immediately devoted himself to the revolutionary struggle. He served as the chairman of the Pennsylvania Public Security Committee, presided over the local military Committee, and drafted the state constitution with Paine. As a representative of Pennsylvania, he attended the Second Continental Congress and became one of the drafters of the American Declaration of Independence. He served as the US Postal Secretary and made great achievements in organizing postal services during the war. As a member of the three-member committee, he negotiated with Washington and decided to mobilize North America 13 state, which made the War of Independence last for six years. Under the situation that Britain is strong and the United States is weak, the colonial people have to fight for foreign aid. Franklin went to France on the orders of the Continental Congress, striving for an alliance between the United States and France and opposing Britain. Under the complicated diplomatic environment that was not conducive to the United States at that time, he took advantage of the contradictions among European countries, seized the favorable opportunity to conclude an alliance and covenant between the United States and France with the belief that the United States would win, perseverance and ingenious diplomatic skills, and won a lot of foreign aid in manpower, material resources and financial resources, thus ensuring the victory of the War of Independence. In the later period of the war, he participated in and presided over the negotiations between the United States and Britain, signed an Anglo-American peace treaty in favor of the United States, and successfully completed the arduous wartime diplomatic mission. He became the first new American ambassador extraordinary and plenipotentiary to France, and stayed in France until 1785. After returning home, he was elected governor of Pennsylvania for four consecutive years. At the American Constitutional Convention, he was a member of the Constitution Drafting Committee. His bicameral parliamentary system, which is used to mediate the differences of the delegates, has become one of the basic national systems in the United States. 1788 will no longer hold public office. However, he still published political articles for the government to choose from and devoted himself to promoting the abolition of slavery. On April 1790, Franklin died. On the day of his funeral, as many as 20,000 people buried him, fully expressing the condolences of the American people. At the same time, not only the US Congress decided to mourn for him for one month, but also the French National Assembly decided to do so.

[Edit this paragraph] 3. Catch lightning

1746, an English scholar made an electrical experiment with a glass tube and a Leyden bottle in Boston. Franklin watched his performance with great interest and was deeply attracted by the emerging electrical science. Then Franklin began to study electricity. Franklin did many experiments at home, studied the properties of two kinds of charges, and explained the sources of electricity and the phenomena existing in matter. Before the eighteenth century, people could not correctly understand what lightning was. At that time, it was generally believed that thunder and lightning were the wrath of God. Some people of insight who don't believe in God have tried to explain the causes of lightning, but in order to succeed, it is more popular in academic circles to think that lightning is a "gas explosion". In an experiment, Franklin's wife Lide accidentally touched the Leyden bottle. When the lightning flashed, Lide was hit and fell to the ground, pale, and lay at home for a week before recovering. Although this was an accident in the experiment, Franklin, who was quick-thinking, thought of lightning in the air. After repeated thinking, he came to the conclusion that lightning is also a discharge phenomenon, which is essentially the same as electricity generated in the laboratory. So, he wrote a paper entitled "On lightning in the sky is the same as our electricity" and sent it to the Royal Society. But Franklin's great idea was ridiculed by many people, and some even ridiculed him as "a madman who wants to separate God from thunder and lightning". Franklin was determined to prove everything with facts. 1752 One day in June, it was overcast with thunder and lightning, and a storm was coming. Franklin and his son William came to an open place with a kite with a metal pole on it. Franklin held the kite high, while his son flew with the kite string. Because of the strong wind, the kite was quickly put into the sky. In an instant, thunder and lightning, pouring rain. Franklin and his son are pulling a kite string together, and the father and son are anxiously looking forward to it. At this moment, just a flash of lightning passed over the kite. Franklin approached the string on the kite with his hand, and there was a terrible numbness at once. He couldn't restrain his inner excitement and shouted, "William, I got an electric shock!" " "Later, he introduced the electricity from the kite line into the Leiden bottle. After returning home, Franklin conducted various electrical experiments with lightning, which proved that lightning in the sky has exactly the same properties as electricity generated by artificial friction. Franklin's hypothesis that electricity in the sky and electricity on the ground are the same thing has been well confirmed in his own experiments. The success of the kite experiment made Franklin famous in the scientific world. The Royal Society gave him a gold medal and hired him as a member of the Royal Society. His scientific works have also been translated into many languages. His electrical research has achieved a preliminary victory. However, in the face of honor and victory, Franklin did not stop further research on electricity. 1753, the famous Russian electrician Lichtman was killed by lightning in order to verify Franklin's experiment, and he was the first victim of electrical experiment. The price of blood makes many people wary and afraid of lightning detection. But faced with the threat of death, Franklin did not flinch. After many experiments, he made a practical lightning rod. He fixed an iron bar several meters long on the roof with insulating material, and a thick iron wire was tightly tied to the iron bar, reaching to the ground. When lightning struck the house, it went straight into the earth along the metal pole through the conductor, and the building was intact. 1754, lightning rod began to be used, but some people think it is ominous, and it will bring drought if it goes against God's will. Steal lightning rods at night. However, science will eventually overcome ignorance. After a gust of lightning and thunder, the cathedral caught fire; High-rise buildings with lightning rods are safe. Facts have educated people and made them believe in science. Lightning rods spread to Britain, Germany, France and finally all over the world. Franklin's contribution to science lies not only in electrostatics, but also in a wide range of research fields. Mathematically, he created the Eight Rubik's Cube and Sixteen Rubik's Cube, which have special properties and complicated changes, and are still praised by scholars. In thermodynamics, he improved the heating stove, which can save three quarters of the fuel, and is called "franklin stove"; In optics, he invented bifocal glasses for the elderly, which can not only see near things, but also see far things. He and hartle of Cambridge University used the evaporation of ether to get a low temperature of minus 25 degrees (Celsius) and founded the theory of evaporative refrigeration. In addition, he also studied meteorology, geology, acoustics and ocean navigation, and made many achievements.

[Edit this paragraph] 4. An outstanding social activist

Franklin was not only an excellent scientist, but also an outstanding social activist. He spent a lot of time in social activities all his life. Franklin attached great importance to education. He established libraries and organized and founded many associations to improve the cultural quality of people from all walks of life. Just as he made new achievements in scientific research, due to the cruel rule of British colonists, the national liberation movement in North American colonies was growing. From 1757 to 1775, he went to Britain as a representative of North American colonies for many times to negotiate. After the outbreak of the War of Independence, he participated in the Second Continental Congress and the drafting of the Declaration of Independence. 1776, 70-year-old Franklin crossed the ocean to France and won the support of the French and European people for the North American War of Independence. From 65438 to 0787, he actively participated in the formulation of the American Constitution and organized a movement against slavery.

Franklin said: "We have benefited a lot from the inventions of our predecessors. We should also be happy to have the opportunity to serve others with any of our inventions. We should do so voluntarily and generously."

[Edit this paragraph] 5. The superstar has fallen

Franklin spent the last winter in the company of his relatives. 1April 7, 790, at night 1 1 point, Franklin died suddenly. At that time, his grandchildren, Temple and Benjamin, were with him. On April 2 1, the people of Philadelphia held a funeral for him. More than 20,000 people joined the funeral procession and mourned for Franklin's death for one month. In this way, Benjamin Franklin passed the 84th spring and autumn period of his life and lay quietly in the grave in the church yard. When Franklin died, the first tombstone was erected. The inscription reads: The second tombstone of printer Benjamin Franklin was erected for him by the masses. The inscription reads: lightning from the sky, civil rights from the tyrant. The two inscriptions sum up two brilliant careers in his life.
