Albert Einstein was born on March 14th,1879 in Germany. When he was a child,he was curious about everything, but he was considered to be slow at learning. In 1886, he began to study in Munich. He studied mathematics as well as religion. In 1896,Einstein graduated from high school at the age of 17.

Four years later, Einstein became a maths teacher. In 1905, he received a doctor’s degree. By the year 1915, he had developed the famous Theory of Relativity and became famous in the world. He proved that light is bent as it passes the sun. Because of his great achievement, he won the Nobel Prize for Physics in 1922.

Einstein was one of the greatest scientists in the 20th century. Some people say that he was a genius. But I think the main reason why he was so successful was his hard work .
