Albert Einstein was born in Ulm, in the Kingdom of Württemberg in the German Empire on 14 March 1879. His father was Hermann Einstein, a salesman and engineer. His mother was Pauline Einstein (née Koch). In 1880, the family moved to Munich, where his father and his uncle founded Elektrotechnische Fabrik J. Einstein & Cie, a company that manufactured electrical equipment based on direct current.
The Einsteins were non-observant Jews. Albert attended a Catholic elementary school
from the age of five for three years. At the age of eight, he was
transferred to the Luitpold Gymnasium (now known as the Albert Einstein
Gymnasium) where he received advanced primary and secondary school
education until he left Germany seven years later.
Although it has been thought that Einstein had early speech
difficulties, this is disputed by the Albert Einstein Archives, and he
excelled at the first school that he attended. He was right handed; there appears to be no evidence for the widespread popular belief hat he was left handed.
His father once showed him a pocket compass; Einstein realized that
there must be something causing the needle to move, despite the apparent
"empty space". As he grew, Einstein built models and mechanical devices for fun and began to show a talent for mathematics. When Einstein was ten years old, Max Talmud (later changed to Max Talmey), a poor Jewish medical student from Poland,
was introduced to the Einstein family by his brother, and during weekly
visits over the next five years, he gave the boy popular books on
science, mathematical texts and philosophical writings. These included
Immanuel Kant's Critique of Pure Reason, and Euclid's Elements (which Einstein called the "holy little geometry book").
In 1894, his father's company failed: direct current (DC) lost the War of Currents to alternating current (AC). In search of business, the Einstein family moved to Italy, first to Milan and then, a few months later, to Pavia. When the family moved to Pavia, Einstein stayed in Munich to finish his studies at the Luitpold Gymnasium. His father intended for him to pursue electrical engineering, but Einstein clashed with authorities and resented the school's regimen and teaching method. He later wrote that the spirit of learning and creative thought were lost in strict rote learning. At the end of December 1894, he travelled to Italy to join his family in Pavia, convincing the school to let him go by using a doctor's note. It was during his time in Italy that he wrote a short essay with the title "On the Investigation of the State of the Ether in a Magnetic Field."
In late summer 1895, at the age of sixteen, Einstein sat the entrance examinations for the Swiss Federal Polytechnic in Zurich (later the Eidgenössische Polytechnische Schule). He failed to reach the required standard in several subjects, but obtained exceptional grades in physics and mathematics. On the advice of the Principal of the Polytechnic, he attended the Aargau Cantonal School in Aarau,
Switzerland, in 1895–96 to complete his secondary schooling. While
lodging with the family of Professor Jost Winteler, he fell in love with
Winteler's daughter, Marie. (Albert's sister Maja later married Wintelers' son Paul.) In January 1896, with his father's approval, he renounced his citizenship in the German Kingdom of Württemberg to avoid military service. (He acquired Swiss citizenship five years later, in February 1901.) In September 1896, he passed the Swiss Matura with mostly good grades (including a top grade of 6 in physics and mathematical subjects, on a scale of 1-6), and, though only seventeen, enrolled in the four-year mathematics and physics teaching diploma program at the ETH Zurich. Marie Winteler moved to Olsberg, Switzerland for a teaching post.
Einstein's future wife, Mileva Marić,
also enrolled at the Polytechnic that same year, the only woman among
the six students in the mathematics and physics section of the teaching
diploma course. Over the next few years, Einstein and Marić's friendship
developed into romance, and they read books together on
extra-curricular physics in which Einstein was taking an increasing
interest. In 1900, Einstein was awarded the Zurich Polytechnic teaching
diploma, but Marić failed the examination with a poor grade in the
mathematics component, theory of functions. There have been claims that Marić collaborated with Einstein on his celebrated 1905 papers, but historians of physics who have studied the issue find no evidence that she made any substantive contributions.
