Bettina von Arnim was born at Frankfurt am Main, into the large Brentano family of an Italian merchants. Her grandmother, Sophie von La Roche, was a novelist, and her brother was Clemens Brentano, the great poet known for his lyric poems, libretti, and Singspiele. He was a mentor and protector to her and inspired her to read the poetry of the time, especially Goethe. From an early age Bettina was called 'the kobold' by her brothers and sisters, a nickname that she maintained later on in Berlin society.
