In 1895, the young Albert tried to enter Zürich Polytechnic, even though he had not finished his high school. After having failed the entrance examination, he decided to attend the last year of a technical school at Aarau, in Switzerland. He lived in Aarau as a guest of the family Winteler. He enjoyed the liberal educational model in force in that school, as well as the exciting new political streams crossing Swiss social life. He asked for Swiss nationality and kept up it for all his life. After having passed the second entrance examination, in autumn 1896, he began to attend Zürich Polytechnic. He spent much time in studying some subjects and disregarded some others but, at the end, he managed to graduate with good marks in 1900. He hoped to win an academic position as assistant but his expectation was not satisfied. As a consequence, he had to look for a different job, in order to support economically himself and the family he desired to form. Since some years, he was in love with Mileva Maric, who studied physics at the Polytechnic. She came from Serbia and was one of the first women who, in late nineteenth century, undertook to study physics. Although Albert’s family did not like that relationship, they got married just after Albert managed to find a job at Bern Patent Office. He did not give up the beloved theoretical physics: the job and the family did not prevent him from studying and taking part to scientific debates involving a small group of friends.
