In 1990, the trestle windmill between Lindhorst and Colbitz was to be sold to Schleswig-Holstein. Mr Friedhelm Sienholz campaigned for its preservation and subsequently restored the mill in order to preserve the last testimony to past techniques and make it accessible to the general public. On 30 October 1990, the "Verein zur Erhaltung der Blockwindmühle Lindhorst e. V." was founded, and Mr Sienenholz has been its uninterrupted chairman ever since. Thanks to his commitment, the mill was restored and a Möllenhus, a bakery and a Möllen barn were built. He often put personal projects on the back burner in order to be active during work assignments. In 2018 and 2020, he collected funding and donations to finance the reconstruction after the bakehouse burned down in 2018 and one wing of the mill was damaged by a storm in 2020. Mr Sienholz was not discouraged by these setbacks. Today, the mill ensemble in Lindhorst is a popular excursion destination.
Mr Dietmar Neubauer has always been committed to the welfare of people who have not been favoured by fate, especially children and young people suffering from cancer at the Pfeiffer Foundations' children's hospice in Magdeburg. He tirelessly collects donations, with a particular focus on the families, relatives and friends of those affected. Even during his professional career, he supported the care of institutionalised children in Loitsche-Heinrichsberg with repairs and donations in kind and endeavoured to make their stay in the facilities more pleasant. For over 30 years, he has generated further donations by selling and auctioning his self-made wooden exhibits at public events and markets. His numerous appeals have already raised more than 50,000 euros.
