Friedrich David Gräter (1768 – 1830) was one of the founders of the field of Scandinavian studies and Germanic philology in Germany.
He worked as a gymnasium teacher of Greek and Hebrew in Schwäbisch Hall from 1804 as rector.
In 1805, Gräter married Maria Elisabetha, née Hofmann, widowed Seiferheld und Haspel, with whom he had a daughter.
He bitterly criticized the Romanticist character of the early publications of the Brothers Grimm.
The enmity between Gräter and the Grimms contributed to a systematic suppression of Gräter's achievements in the earlier history of the field; in the opinion of Heinrichs (1986), the Grimms "all but succeeded in suppressing the founder of scholarly Nordic studies in Germany.
