The Brunnen brand was introduced in 1894 and originated from the paper processing company Baier & Schneider in Heilbronn, north of Stuttgart. The founders recognized the importance of paper and the roll liner machine early on. During the interwar period, the brand established itself and successfully sold its business and notebooks. A decade after World War II and the reconstruction of the destroyed company site, the demand for paper products began to rise rapidly. Today, the company is run by a great-grandson and a great-great-grandson of one of the founders. In addition to notebooks, calendars, and other stationery items, a wide range of office and school supplies has been added over time. However, what has not changed is the company philosophy: Brunnen remains open to new ideas and is committed to continuously impressing customers with the high quality of its products.
