In fact, 4,5 stars. Very interesting and informative, but last pages were not so good as the first 2/3 of the book.

Who Was…? biography series for middle grade aw-inspires with the story of Nikola Tesla who was one of the most brilliant and influential scientists of all time, whose experiments with electricity, remote control, and wireless communication changed the world.

Nikola Tesla (1856-1943) was born in Smiljan, now Croatia. His family was Serbian. Nikola from childhood had a natural instinct for figuring things out. His mother was not educated but she had an inventive side.

When he was four, he followed his mother’s example by experimenting and coming up with his own ideas.

When he was five, he created a spinning wheel on a stream, which showed him how energy was created to spin the wheel.

When he was seven, his family moved to Gospic town. Nikola didn’t like the city. He missed his village where he experimented with his waterwheels. To fill the void, he became an avid reader, reading through the night. In one of the books, he read about Niagara Falls. It became his dream to create a giant waterwheel to create power.

At school, he proved to be very good at math. He could easily solve an equation in his head.
At Gymnasium, he liked electrical and mechanical experiments the most.

At Higher Gymnasium (High School), he was impressed with his science classes and experiments. He always had a thousand questions after an experiment.

His heart was set on research and made up his mind to become an electrical engineer, but his father wanted him to become a priest. It was during a time when cholera broke out and Nikola got sick. When Nikola was fighting for his life, his father agreed for him to study electrical engineering.

Nikola went to university in Gratz, Austria. As always, he worked tirelessly. He slept only four hours a night. In his second year, a machine arrived from Paris which forced an electrical current to move in only one direction. Nikola argued it would be better to let the current flow back and forth, but it was never done to power a motor. He couldn’t get it work and got frustrated and dropped out in his third year.

When his father died, he felt an obligation to help in supporting his mother. Thus, he looked for a job. His uncle’s friend built a telephone exchange in Budapest, Hungary. Nikola worked as its chief engineer. He made many improvements. Meanwhile, he was still thinking about alternating current (AC).

One day, when he walked in a park with his friend reciting poetry, it came to him. The answer were the magnets to reverse the direction of an electric current.

In 1882, Nikola went to Paris to work for Edison Company. In his spare time, he built a model, but he couldn’t find an investor to build an entire system. His boss suggested that he went to New York to work for Edison Company.

In New York, he worked long hours as Thomas Edison himself. When Nikola completed a project and didn’t receive a promised bonus, he left Edison.

He was broke and hungry. He went to dig ditches which turned out to be his big break. The foreman overheard him talking about his AC (Alternating Current) motor, and he knew an expert electrician, who was Alfred Brown.

Nikola and Alfred opened a laboratory in NYC in 1886 to develop patents on AC technology. His patent ideas got an attention of George Westinghouse, the owner of the Westinghouse Electric Company, who was a competitor of Thomas Edison. Westinghouse offered a huge amount for the patents and Nikola accepted.

Now, Nikola had freedom to open his own laboratory and work on his ideas.
Westinghouse Corporation was awarded contract to build turbines and generators for Niagara Falls using Nikola’s patents and AC technology.

Nikola’s next goal was wireless communication. His ideas were way ahead of his time, but technology had to catch up to his ideas.

Later, his ideas were getting stranger.

Nevertheless, after his death, his reputation grew and he continued to be honored for his brilliance and his many scientific developments.

This biography exhibits a man who was way ahead of his time. His mind was influenced by his mother’s curiosity to experiment. From childhood, that propelled Nikola to explore his natural instinct with experiments, mostly the ones exploring energy that led to electricity as it fascinated him the most. Despite some challenges, he never lost his fuel for his passion.

As a degreed Electrical Engineer I'm ashamed to admit, but I will, that I first learned about Tesla (T) as a derived unit of measure used to express the strength of a magnetic field. As with many units of measure in various scientific fields, I eventually learned that the Tesla was named in honor of Nikola Tesla, a giant figure in the field of electronics. He came from humble beginnings and he loved to experiment, especially with anything electrical. Eventually arriving penniless in America with a letter of introduction to Thomas Edison with whom he did important work. After a falling out he became Edison's major competitor. Holder of some 700 patents in the US and Europe his inventions and scientific breakthroughs are way too numerous to list but notably he developed the concepts and applications for AC current, remote controls, wireless communications, robotics, newer forms of turbine engines, and the Tesla Coil. Much of what he developed formed the basis for modern technology and products that are commonly used today. Sadly, many today only recognize Tesla as a name for a line of electric vehicles. Who Was Nikola Tesla by Jim Gigliotti is a short book that is brimming with facts about the life of one of the most prolific inventors in human history. It is well researched and will hold your interest no matter who you are or what your interests.

Am rămas impresionată de această serie de cărți. E potrivită copiilor de 7+ ani.
Nu le avem pe toate, dar o să le avem neapărat.
Cărțile curpind foarte multe detalii din viața multor oameni influenți ai lumii, cei care au schimbat cursul vieții noastre spre bine.

Informațiile sunt bine adaptate copiilor și cărțile conțin multe ilustrații care sunt foarte atrăgătoare pentru copii. Pentru că ei (copiii) vizualizează foarte bine ceea ce citesc, le găsesc loc în biblioteca noastră.

i'm not sure how to rate a children's biography— obviously it's below my reading level, and the information is abridged to account for this, so by enjoyment? 3 stars.

I didn't know much about Nikola Tesla so it was fun to read more about him. He really was a genius.

I thought it was interesting to read how fastidious he was. He didn't like shaking hands and was pretty OCD about things. He had to eat dinner at the exact same time each night.

What made me sad was that he pretty much died alone and broke. That seems to happen so much to a lot of famous people. I was glad that his old company stepped up to take care of him.

Great series! On a side note, I recently watched the Netflix show and it was a lot of fun!

I'm really glad I read this. It nicely compresses a lot of complicated details of Tesla's life and inventions into an easy to read book. I was really interested to learn about the relationship between Edison and Tesla and this book gives some good insight without being biased.

Ồ, quyển này thú vị hơn mình nghĩ.

Quả thật trước khi đọc quyển này, mình chẳng biết Nikola Tesla là ai, dù có từng nghe cái tên này ở đâu đó. Đến lúc đọc quyển sách này mới biết, hóa ra ông là cha đẻ dòng điện xoay chiều, đọc sách rồi mới nhớ đến Vật lý cấp ba có từng biết đến đơn vị Tesla về cường độ cảm ứng từ, cũng nhớ ra là đã từng nghe đến dòng xe được đặt tên là Tesla nữa. ^^

Tesla là người có rất nhiều ý tưởng sáng tạo, các thiết bị hiện đại như điện thoại di dộng, Internet, GPS, radio, ti vi, radar, đèn neon đều đặt nền móng từ các ý tưởng của ông ấy. Sách viết ngắn gọn, dễ hiểu nhưng khá cuốn hút, đủ để khái quát về cuộc đời ông, giúp người đọc hiểu thêm về quá trình đi từ ý tưởng đến phát minh và ứng dụng chúng để trở thành những đồ vật vô cùng quen thuộc với cuộc sống mình ngày hôm nay.

I love reading this books with my son, recently he wants to read them on his own. So, this is the firs one i've read in awhile. I really enjoyed this book, the author did a good job talking about the important bits of Nikola Tesla's life, and I learned a lot throughout the book that I hadn't realized before.

I perused a few books about Nikola Tesla, wanting a basic biography about his personality and brilliant, inventive mind that wouldn't get too complex or too mathematical, and this book was pitch-perfect. It gives the kind of man-behind-the-myth view I was looking for.

This is the kind of chapter book that both children and adults will find interesting. There's a nice blend of life chronology and quirky facts about him. The illustrations are also both imaginative and factual, adding to the reading experience.

This book will fit in well in school and public libraries as well as personal book shelves. It would make a great gift, too. I'm likely to check out more in this series. I've recommended this to my nieces who are in upper grades in elementary school as well as to my sister (we both love biographies and memoirs--she also read it and we had a fun chat on what we learned about Tesla).

چون زندگی‌ش خیلی پستی بلندی داشت
و باید خیلی مفصل دربارش،

اما یه جورایی چپونده شده بود یه بخشاش...
اما بازم، ارزش خوندن داره...
و بهترین بخشش توضیح کودکی_نوجوانیشه

This book is great for kids. Understandably watered down, I am glad that it did discuss Edison's thuggish behavior. That man was a criminal.

Nikola Tesla is one of the most important men who ever lived, and if he was protected, funded and appreciated during his time our civilization would be at least 500 years ahead at this point in time.

Biography: Who was Nicholas Tesla
Lexile level: 900L
Grades: 3 – 7
Ages: 8 -12
Get ready for the electrifying biography of Nikola Tesla–part creative genius, part mad scientist, and 100% innovator.
A great way to introduce this book to the class is to talk about tesla motor car company. Most of the children will have heard of Tesla cars, and I can share the fact that Tesla, Inc. is a line of cars named in his honor. This will quickly draw attention and students will enjoy learning about this amazing inventor. In many ways Nikola is similar to Elon Musk, a modern-day inventor and the man who started Tesla Inc. Cars.
“An inventor who once worked with Thomas Edison
An engineer whose experiments with electricity, remote control, and wireless communication changed the world.
One of the most brilliant and influential scientists of all time
When Nikola Tesla arrived in the United States in 1884, he didn’t have much money, but he did have a letter of introduction to renowned inventor Thomas Edison. The working relationship between the two men was short lived, though, and the two scientist-inventors became harsh competitors. One of the most influential scientists of all time, Nikola Tesla is celebrated for his experiments in electricity, X-rays, remote controls, and wireless communications. His invention of the Tesla coil was instrumental in the development of radio technology.”
This is a wonderful book about a boy who was a dreamer, he could see in his head what he wanted to build, he tested his theories in his head until he knew they would work, then he built them. He was way ahead of his time, he had ideas of about things that other people were not even thinking off.
This is a great book to have in the classroom, if read independently it will encourage students to think about inventing, engineering, experiments, math and science in new and interesting ways. Students could choose to do a presentation on Nikola, talking not only about the inventor, but the time he lived in, a little lesson in history about how things were done in the time period between 1850 and 1940.
One really interesting thing about this book is that Nikola was an immigrant! He talks about what it was like to live in the country he grew up, why he chose to travel to another country, how he got there, and why he chose to stay.
There are several ways I would use this book in the classroom, a history book, a book for math and science, a book for a character to study for a wax museum presentation, a book about a boy and his struggles as he grew up, a book club book for small group discussion, and/or an inspirational book about what you can do and accomplish when you really want to make it happen.

Designed alternating current (AC) that enabled high voltage currents to travel long distances, then transform it back to low voltage current that is safe to use. It differed from Thomas Edison’s direct current (DC) which could only travel short distances, thus, requiring many power plants to be built to power all the homes

Tesla worked with George Westinghouse, who purchased his AC parents. Tesla later gave up his royalties under the patents to help Westinghouse survive financially. Westinghouse and Edison competed in the current wars. Edison tried to convince people that AC was unsafe and even electrocuted stray dogs with AC. But Westinghouse won contract to power the Chicago World Fair and convinced people of the safety of AC. Westinghouse won contract to build generators at Niagara Falls.

Tesla narrowly missed out on patent for radio transmission but invented the Tesla coil, which helped improved transmissions. He foresaw possibility of cell phones and Internet with wireless transmissions.

we learn from the man who made the electric age possible:
To read, and keep reading. He said once, "Of all things , I liked books the most."

Usw our imagination because It is the key to being a genius just like him.

We have to build strong relationships and friendships because we might need them , and we will learn from their experiences. but we have to make sure that they don't use us .

The mistakes he made are :
he didn't get married, so he ended up with him alone .

He overworked himself , put pressure on himself so he endangered his health, especially he wasn't sleeping enough and wasn't eating well.
He had an unhealthy lifestyle!

I chose the book because I wanted to learn about someone's life. Nikola was quite a crazy person as he wanted to see if he could fly just by going up a second story building and holding an umbrella out the window while jumping out of it and also how he was wanting to build a death ray to end all wars.

I feel like I need to do more research into Tesla before I can decide that this book is truly accurate in its telling. Some things seemed biased, but I also know that information about Tesla ha been tainted over the years. Still a good introduction for children to his works and importance in history.

Excellent book. I read Who Was Thomas Edison? and then followed by reading this one. It was fascinating to read about the competition between the men and how they nurtured their ideas. This book read as if it were fiction. It was a very interesting book and full of adventure and interesting bits about his life.

This was a very enlightening book filled with information on Nikola Tesla. He is one of the lesser known inventors of the twentieth century. He helped develop the alternating current of electricity that we now use in many products today. He was constantly inventing new ideas. The reader will learn many new things about his life and inventions by reading this book.

This book starts from the beginning of Nikola Tesla's life, and goes through all of the main events that happen to him. It elaborates on things like who Thomas Edison was for younger children who may not know exactly what he was known for. This would be a perfect book to use in a lesson on electricity and how we got to where we are today.
