Johann Karl Simon Morgenstern was a Livonian philologist, the first director of the library of the Imperial University of Dorpat. He coined the term Bildungsroman.

Morgenstern was born in Magdeburg. He studied at the University of Halle under Johann August Eberhard in philosophy and Friedrich August Wolf in philology.

In 1802 he moved to Dorpat where he would spend the rest of his life. He held the chair for rhetoric, classical philology, aesthetics, and history of art and literature at the newly refounded University of Dorpat and was the first director of its library.

The character of his work changed in Dorpat. He discontinued his Plato studies and wrote about literature, art, philology, and philosophy. Morgenstern's former teacher Friedrich Wolf was disappointed by this development, and he remarked in 1808 that his student was growing more elegant, vain, and boring with the years.[1] It was in the course of this work that Morgenstern coined "Bildungsroman".

Even after his retirement in 1834 Morgenstern stayed in Dorpat. He bequeathed his 12,000-volume library, containing many manuscripts and a good part of the Kant estate, to the university
