Under Heinrich's direction, the business flourished. In 1831 he purchased the publishing house J.F. Gledisch, a firm which could trace its origins back to the seventeenth century. In 1837 he launched the "Leipziger Allgemeine Zeitung" (subsequently expanded and later relaunched as the Deutsche Allgemeine Zeitung), a newspaper which under his proprietorship had a reputation as a middle-class liberal publication.
