Paderborn is the largest city in the district of the same name and one of the regional centres of East Westphalia-Lippe, the north-eastern part of North Rhine-Westphalia. It is a cathedral and university city: Paderborn University gives it a strong profile in computer science and engineering, and research institutes such as the Fraunhofer Institute for Mechatronic Systems Design (Fraunhofer IEM) work closely with regional industry. Linnemann served as a member of the Fraunhofer IEM’s board of trustees (Kurator) from 2016 to June 2026, according to his Bundestag disclosures.
Altenbeken, where he sat on the council, is a smaller municipality in the Egge hills. It is best known as a railway location: its large stone railway viaduct is one of the landmarks of the region, and the village grew around the railway junction in the nineteenth century.
The surrounding district combines towns, villages and agricultural land with a dense network of manufacturing companies. Across East Westphalia-Lippe, family-owned firms in mechanical engineering, electrical and automation technology, furniture, food and IT services are characteristic — the kind of Mittelstand economy that would later become the focus of Linnemann’s work in the Mittelstands- und Wirtschaftsunion.
Beyond politics in the narrow sense, his regional ties include the founding and board chairmanship of the Stiftung LEBENSlauf (since 2010), the vice-presidency of the football club SC Paderborn 07 (2018 to August 2026) and the chairmanship of the advisory board of the association Neue Mobilität Paderborn e.V., all listed in official sources.
