Einstein was born in 1879 in a Jewish family in Ulm, Germany (both parents were Jewish). He graduated from the Federal Institute of Technology in Zurich in 1900 and became a Swiss citizen. In 1905, after receiving a doctorate in philosophy from the University of Zurich, Einstein proposed the photon hypothesis and successfully explained the photoelectric effect. As a result, he won the 1921 Nobel Prize in Physics and founded the special theory of relativity in 1905. Founded the general theory of relativity in 1915. Died on April 18, 1955, at the age of 76.

In 1921 (42 years old), Einstein won the Nobel Prize in Physics for his research on the photoelectric effect. His research promoted the development of quantum mechanics. In January, visited Prague and Vienna. On January 27 of the same year, he gave a report on "Geometry and Experience" at the Prussian Academy of Sciences. In February, I went to Amsterdam to attend the International Federation of Trade Unions conference.

From April 5 to May 30, in order to raise funds for the establishment of the Hebrew University of Jerusalem, he and Weizmann visited the United States for the first time. Received the Barnard Medal from Columbia University. Received by President Harding at the White House. During his visits to Chicago, Boston and Princeton, he gave four lectures on the theory of relativity. In June, he visited the UK and paid a visit to Newton's Cemetery.
