Albert Einstein was a famous physicist. His research spanned from quantum mechanics to theories about gravity and motion. After publishing some groundbreaking papers, Einstein toured the world and gave speeches about his discoveries. In 1921 he won the Nobel Prize for Physics for his discovery of the photoelectric effect.

What is Albert Einstein known for?
Albert Einstein is best known for his equation E = mc2, which states that energy and mass (matter) are the same thing, just in different forms. He is also known for his discovery of the photoelectric effect, for which he won the Nobel Prize for Physics in 1921. Einstein developed a theory of special and general relativity, which helped to complicate and expand upon theories that had been put forth by Isaac Newton over 200 years prior.
How Albert Einstein Developed the Theory of General Relativity
Learn more about why it took Albert Einstein years to express his ideas mathematically.
Einstein’s parents were secular, middle-class Jews. His father, Hermann Einstein, was originally a featherbed salesman and later ran an electrochemical factory with moderate success. His mother, the former Pauline Koch, ran the family household. He had one sister, Maria (who went by the name Maja), born two years after Albert.
Einstein would write that two “wonders” deeply affected his early years. The first was his encounter with a compass at age five. He was mystified that invisible forces could deflect the needle. This would lead to a lifelong fascination with invisible forces. The second wonder came at age 12 when he discovered a book of geometry, which he devoured, calling it his “sacred little geometry book.”

All About Einstein
Einstein became deeply religious at age 12, even composing several songs in praise of God and chanting religious songs on the way to school. This began to change, however, after he read science books that contradicted his religious beliefs. This challenge to established authority left a deep and lasting impression. At the Luitpold Gymnasium, Einstein often felt out of place and victimized by a Prussian-style educational system that seemed to stifle originality and creativity. One teacher even told him that he would never amount to anything.
Yet another important influence on Einstein was a young medical student, Max Talmud (later Max Talmey), who often had dinner at the Einstein home. Talmud became an informal tutor, introducing Einstein to higher mathematics and philosophy. A pivotal turning point occurred when Einstein was 16 years old. Talmud had earlier introduced him to a children’s science series by Aaron Bernstein, Naturwissenschaftliche Volksbucher (1867–68; Popular Books on Physical Science), in which the author imagined riding alongside electricity that was traveling inside a telegraph wire. Einstein then asked himself the question that would dominate his thinking for the next 10 years: What would a light beam look like if you could run alongside it? If light were a wave, then the light beam should appear stationary, like a frozen wave. Even as a child, though, he knew that stationary light waves had never been seen, so there was a paradox. Einstein also wrote his first “scientific paper” at that time (“The Investigation of the State of Aether in Magnetic Fields”).
