Hans Arp’s second wife Marguerite Arp-Hagenbach contributed a large part of the estate of Hans Arp and Sophie Taeuber-Arp to the Stiftung Arp e.V.‘s collection. The Foundation therefore possesses a considerable part of the artistic estate of both artists and an archive of historic documents. The collection is supplemented by a library.

In 2010 the Stiftung Arp e.V. opened its archive for research purposes. “Hans Arp Skulpturen. Eine Bestandsaufnahme” (Stuttgart 2012), edited by Arie Hartog with the assistance of Kai Fischer, was published in 2012. This publication provides a comprehensive catalogue and analysis of all heretofore known casts of the sculpture of Hans Arp and their provenance. In addition to including Hartog’s data on these works, the online database encompasses the latest supplementary information. Updated continuously, it reflects the most current state of research.

In the future, it is planned to include work by Hans Arp in different media, including relief, drawing and printmaking in the database. Sophie Taeuber-Arp’s work will also be entered gradually.

We welcome information on works by Hans Arp and Sophie Taeuber-Arp in public and private collections or with as-yet unknown provenance. Submitted information will be handled with the utmost confidence. The information may be sent to:
