The German-born
physicist Albert Einstein developed the first of his groundbreaking theories
while working as a clerk in the Swiss patent office in Bern. After making his
name with four scientific articles published in 1905, he went on to win
worldwide fame for his general theory of relativity and a Nobel Prize in 1921
for his explanation of the phenomenon known as the photoelectric effect. An
outspoken pacifist who was publicly identified with the Zionist movement,
Einstein emigrated from Germany to the United States when the Nazis took power
before World War II. He lived and worked in Princeton, New Jersey, for the
remainder of his life.
Born on March 14, 1879,
in the southern German city of Ulm, Albert Einstein grew up in a middle-class
Jewish family in Munich. As a child, Einstein became fascinated by music (he
played the violin), mathematics and science. He dropped out of school in 1894
and moved to Switzerland, where he resumed his schooling and later gained
admission to the Swiss Federal Polytechnic Institute in Zurich. In 1896, he
renounced his German citizenship, and remained officially stateless before
becoming a Swiss citizen in 1901.
While
at Zurich Polytechnic, Einstein fell in love with his fellow student Mileva
Maric, but his parents opposed the match and he lacked the money to marry. The
couple had an illegitimate daughter, Lieserl, born in early 1902, of whom
little is known. After finding a position as a clerk at the Swiss patent office
in Bern, Einstein married Maric in 1903; they would have two more children,
Hans Albert (born 1904) and Eduard (born 1910).
Einstein’s Miracle Year (1905)
While
working at the patent office, Einstein did some of the most creative work of
his life, producing no fewer than four groundbreaking articles in 1905 alone.
In the first paper, he applied the quantum theory (developed by German
physicist Max Planck) to light in order to explain the phenomenon known as the
photoelectric effect, by which a material will emit electrically charged
particles when hit by light. The second article contained Einstein’s
experimental proof of the existence of atoms, which he got by analyzing the
phenomenon of Brownian motion, in which tiny particles were suspended in water.A
In
the third and most famous article, titled “On the Electrodynamics of Moving
Bodies,” Einstein confronted the apparent contradiction between two principal
theories of physics: Isaac Newton’s concepts of absolute space and time and
James Clerk Maxwell’s idea that the speed of light was a constant. To do this,
Einstein introduced his special theory of relativity, which held that the laws
of physics are the same even for objects moving in different inertial frames
(i.e. at constant speeds relative to each other), and that the speed of light
is a constant in all inertial frames. A fourth paper concerned the fundamental
relationship between mass and energy, concepts viewed previously as completely
separate. Einstein’s famous equation E = mc2 (where “c” was the constant speed
of light) expressed this relationship.
