About the Author
This chapter is a short life story written for your school book by the NCERT team. There is no one famous writer named here – it's made to teach students about great people. The real hero is Albert Einstein, and the story shows why his mind was so special. Einstein himself wrote many science papers, but this chapter is about his whole life, not by him.
What’s the Story About?
This is a true tale about Albert Einstein from when he was a baby to an old man. It's not like a movie with fights – it's about how a quiet, odd boy became the world's best thinker and helper for peace. Let's go step by step in simple words.
Albert was born on March 14, 1879, in a city called Ulm in Germany. His mom was scared because his head looked too big, and she thought he was a strange kid. He didn't speak until he was two and a half years old. When he finally talked, he repeated every word two times, like an echo. Other kids didn't play with him much, so he stayed alone, making tall houses from playing cards or fixing toys. He loved things that moved, like machines.
At age six, his mom made him learn violin music, and he got really good at it later. But school was tough – teachers were strict, and he hated learning by heart. One teacher called him "brother boring" because he didn't talk much. The school boss told his dad that Albert would never do well in life. So, at 15, Albert left school without a certificate. His parents moved to Italy, but he stayed in Germany first, then went to Switzerland for a freer school. There, he scored top marks in math and science but failed in other things like history.
In college, he met a smart girl named Mileva from Serbia. She was also studying physics like him. They fell in love, studied together, and got married in 1903. They had two sons. But Albert's job was simple – he checked new inventions in an office. In his free time, he thought about big questions like time, space, and light.
In 1905, at age 26, he shared his famous idea called the "special theory of relativity." It says that time can slow down if you move very fast, and energy (E) equals mass (m) times speed of light squared (c²) – that's E=mc²! People were amazed. Then in 1915, he made another big idea about gravity pulling things in space. For this, he won the Nobel Prize in 1921, the biggest award for science.
But home life was sad – he and Mileva fought a lot because she was also smart but couldn't work much. They separated in 1919, and he married his cousin Elsa the same year. Elsa helped him a lot.
In 1933, bad leaders called Nazis took power in Germany and hated people like Einstein (he was Jewish). So, he moved to America for safety. There, he taught in a big school. But he worried about wars. He wrote a letter to US President Roosevelt saying Germany might make a super bomb (atom bomb), so America should make it first. America did, and used it on Japan in 1945 to end World War II. Einstein felt very sad about the deaths and said it was a mistake.
For the rest of his life, he worked for no more wars and a world government for peace. He died in 1955 at age 76, but his ideas still help scientists today.
In short: From a slow kid to a genius who explained the universe and fought for kindness. The story shows that real beauty is in your mind and heart, not looks!

Themes and Moral
Themes (Big Ideas – like messages in the story):
- Different is Good: Einstein seemed strange as a kid, but his unique mind made him great. Don't judge by looks!
- Science Changes World: His ideas about time, space, and energy help us understand stars and machines today.
- Peace Over War: He hated bombs and worked for friends between countries.
- Family and Love: Marriage can be hard, even for smart people, but support matters.
- Hard Work and Thinking: He didn't give up – thought deeply in simple jobs.
