On 26 May 1799, Spengler's maternal great-grandfather, Friedrich Wilhelm Grantzow, a tailor's apprentice in Berlin, married a Jewish woman named Bräunchen Moses ( 1769–1849, whose parents, Abraham and Reile Moses, were both deceased by that time. Shortly before the wedding, Moses was baptized as Johanna Elisabeth Anspachin (the surname was chosen after her birthplace—Anspach). The couple had eight children (three before and five after the wedding), one of whom was Spengler's maternal grandfather, Gustav Adolf Grantzow (1811–83)—a solo dancer and ballet master in Berlin, who in 1837 married Katharina Kirchner (1813–73), a nervously beautiful solo dancer from a Munich Catholic family; the second of their four daughters was Oswald Spengler's mother Pauline Grantzow. Like the Grantzows in general, Pauline was of a Bohemian disposition, and, before marrying Bernhard Spengler, accompanied her dancer sister on tours. She was the least talented member of the Grantzow family. In appearance, she was plump and a bit unseemly. Her temperament, which Oswald inherited, complemented her appearance and frail physique: she was moody, irritable, and morose.
