About
Paapst Group B.V. is a private holding company registered in the Netherlands. It holds all of its portfolio companies in full, so each one can be developed with a long-term view and without outside shareholders.
The group carries the Paapst family name and coat of arms. The Dutch Paapst family descends from Johann Christian Pabst, born in Emden, Germany, in 1763. His son Harm Friederich settled in the Netherlands around 1822, where the name was registered in error as “Paapst” — the spelling his descendants still carry. The oldest known ancestor, Jan Paap, was born in Harlingen around 1595.
The crest reflects that history: the golden harpy from the arms of Emden, a tilting helm for the family's German origin, a papal tiara for the medieval names Pabst and Paap, and goose quills for an ancestor who served as Emden's toll clerk.
