The foundation's purpose is to support all descendants and their spouses of Dr. Benjamin Sieber, born on May 28, 1839, in Wiesloch, deceased on October 30, 1908, with citizenship in Riedholz, who have been resident in Attisholz, municipality of Riedholz, and who have personally or professionally fallen into financial difficulties through no fault of their own and are unable to overcome them with their own means. Additionally, the foundation can promote the sense of togetherness among the Sieber descendants through regular gatherings. The foundation ensures that a publicly accessible family archive is maintained. Furthermore, the foundation is concerned that the memory of the founder is duly honored.
