Glueckel of Hameln (c. 1646 – September 19, 1724) was a German Jewish businesswoman and diarist. Written in her native tongue of Western Yiddish over the course of thirty years, her memoirs were originally intended to be an ethical will for her children and future descendants; her diaries are the only known pre-modern Yiddish memoirs written by a woman. The Memoirs of Glueckel of Hameln provide an intimate portrait of German-Jewish life between the late seventeenth and early eighteenth centuries and have become an important source for historians, philologists, sociologists, literary critics, and linguists.
