Albert Einstein was a German physicist born in 1879 who developed the theory of relativity and explained the photoelectric effect and Brownian motion. He was born in Germany but obtained Swiss citizenship after studying at the Federal Polytechnical School of Zurich. Einstein published four groundbreaking scientific papers in 1905 that established him as one of the greatest scientists of the 20th century, including his mass-energy equivalence formula E=mc2. He later taught at universities in Bern, Prague, and Berlin before moving to the United States in 1932 to escape the rise of Nazism, where he spent the rest of his life teaching and researching.

life, his family, their experiments and his occupations.

3. Albert Einstein was a German physicist of the nineteenth and
twentieth centuries who was born on March 14, 1879 and died on
April 18, 1955,known mainly for the developmentof the theory of
relativity, the theoretical explanation of Brownian motion and effect
photoelectric.
He was born in the German city of Ulm, but a year later his family
moved to Munich, where he would live until he was 15 years old.
With 17 he entered the Federal Polytechnical Schoolof Zurich to
study mathematics and physics. Five years later, already graduated,
it obtained the Swiss nationality and in 1902 it began to work in the
Federal Officeof the Intellectual Property of Switzerland, a job that
combined until the 30 years with his scientific investigations.
1905 was its most fruitful year, the result of the publication of four
scientific articles on the photoelectric effect,Brownian motion,
specialrelativity theory and mass-energy equivalence (E = mc²).
The first earned him the Nobel Prize in Physics in 1921,the second
his doctoral degree and the last two would consecrate him, in time,
as the greatest scientistof the twentieth century.
In 1908 he began to practice as a professorof physics at the
University of Bern, a post that would continue later years in Prague
and finally in Berlin, where he lived until the rise of the Nazi regime
made him leave Germany and move to the United States (1932 ).
There he taught at the Institute of Advanced Studies in Princeton,
nationalized American (obtaining dual Swiss-Americannationality)
and spent the rest of his life trying to integrate the physical laws of
gravitation and electromagnetismas well as spreading pacifist,
socialist and Zionists until his death by an internal hemorrhage the
18 of April of 1955 (76 years).
