Though never the author of a major book, Rahel Varnhagen is remembered both for the intensity and variety of her correspondence. Six thousand letters have survived, out of an estimated ten thousand letters written by her in the course of her lifetime. A few of her essays were published in "Das Morgenblatt", "Das Schweizerische Museum," and "Der Gesellschafter;" in 1830, her "Denkblätter einer Berlinerin" was published in Berlin. Her husband, Karl August, edited and published her correspondence in the twenty years following her death. Her correspondence with David Veit and with Karl August was published in Leipzig, in 1861 and 1874–1875 respectively.
