Einstein graduated with his Masters degree in 1900, but was unable to find an academic job. He worked in a patent office, while working on his ideas and in 1905 publishing his four groundbreaking *annus mirabilis' papers, and also getting his PhD in 1905. But it was only after he was already famous that in 1909 he got a position in a university.
