It having been decided, perhaps because the downfall of Napoleon shut the door of all other opportunity, that Heine should embark upon a mercantile career, he was given a brief apprenticeship, in 1815 at Frankfurt, in the following years at Hamburg, under the immediate patronage of his uncle Salomon who, in 1818, even established the young poet in a dry goods business of his own. The only result of these experiments was the demonstration of Heine’s total inaptitude for commercial pursuits. But the uncle was magnanimous and offered his nephew the means necessary for a university course in law, with a view to subsequent practice in Hamburg. Accordingly, after some brushing up of Latin at home, Heine in the fall of 1819 was matriculated as a student at the University of Bonn.
In spite of failure to accomplish his immediate purpose, Heine had not sojourned in vain at Hamburg. He had gained the good will of an opulent uncle whose bounty he continued almost uninterruptedly to enjoy to the end of his days. But in a purpose that lay much nearer to his heart he had failed lamentably; for, always sensitive to the charms of the other sex, Heine had conceived an overpowering passion for his cousin Amalie, the daughter of Salomon, only to meet with scornful rebuffs at the hands of the coquettish and worldly-minded heiress. There is no reason to suppose that Amalie ever took her cousin’s advances seriously. Her father certainly did not so take them. On the other hand, there is equally little reason to doubt the sincerity and depth of Heine’s feelings, first of unfounded hope, then of persistent despair that pursued him in the midst of other occupations and even in the fleeting joys of other loves. The most touching poems included among the Youthful Sorrows of his first volume were inspired by Amalie Heine.
At Bonn Heine was a diligent student. Though never a roysterer, he took part in various extra-academic enterprises, was a member of the Burschenschaft, that democratic-patriotic organization so gravely suspected by the reactionary governments, and made many friends. He duly studied history and law; he heard Ernst Moritz Arndt interpret the Germania of Tacitus; but more especially did he profit by official and personal relations with A.W. Schlegel, who taught Heine what he himself knew best, namely, the secret of literary form and the art of metrical expression.
