this is from a bulletin board, so not sure how true it ishttp://boards.straightdope.com/sdmb/archive/index.php/t-625641.htmlQuoteEinstein's salary at the Swiss patent Office was 3500 swiss francs per year in 1903 (for a 6-day, 48-hour work week). (This was about double that of a University Assistant Professor.) In 1904, the Patent Office made his temporary position a permanent one, and raised his salary to 3900 per year. By 1906, he was an 'expert (second class) and earned 4500 swiss francs per year.In 1906, he receives his PhD. (Yes, all his annus mīrābilis papers of 1905 were written before he received his doctorate.)Then in 1909, the University of Zurich created a new professorship in 'theoretical physics' and hired him for the job. They got him by paying him the same salary he was receiving at the Patent Office, 4500 francs per year.During much of this period, Einstein was very poor, living in very constrained circumstances. He had a wife & child to support, plus an ex-wife and child. To earn additional income, he obtained a teaching certificate in 1907, and in 1908 he taught a course in mathematics through the University of Bern. The classes were held early in the morning or in the evening, because he was still working an 8-hour day at the Patent office. Alas, his largest class had only 3 students.
