- 1929 The son, Guenther Authenrieth, takes over the family business. Despite the global economic crisis, war and monetary reform, he established sound economic foundations.

1800 - 1900
- 1893 Constantin Authenrieth takes over the factory. For almost four decades Constantin Authenrieth devised structural and mechanical improvements, always aspiring to bring only quality products to the market under the name of PUCARO (short for Pressspan- und Cartonfabrik Christian Authenrieth Roigheim - Presspaper and Cardboard factory Christian Authenrieth Roigheim).
- 1872 Christian Authenrieth buys the papermill in Roigheim bringing new technology to the venerable workshop. Up till then, the mould-made paper had been moulded manually using old, traditional methods. Outward evidence for this change was the construction of a steam boiler house.
- 1854 Christian Authenrieth founded the firm of Authenrieth.
- 1840 For the first time, the papermill is expressly called a paper factory.
