The Ursula Hauser Collection donation includes five early sculptures, made between 1971 and 1977, rooted in Signer’s explorations of water; its energy, fluidity, elasticity, and cohesive properties. Grosser Tropfen (Big Drop), for example, centers on the formation and tension of a water droplet right before it falls. As is often the case in his work, we encounter an arrangement that is neither purely artistic nor a mere naturalistic observation. In this in-between space, Signer plays with our expectations, challenges our assumptions, and expands our perspectives on art and natural phenomena.

Additionally, the generous donation from Ursula Hauser Collection includes sculptures from the 1990s— such as Hauptstrasse und Nebenstrassen(Main Street and Side Streets), Bett(Bed), and Aquarium—which are being shown here for the first time. Alongside these works, the temporally and thematically related interactive sculpture Wellenapparat  (Wave Apparatus) from the collection of Kunstmuseum St. Gallen is on display. Signers' miniature model mimics a wave's movement, elegance, and dynamic.

Roman Signer's work has been exhibited in solo exhibitions in renowned museums worldwide, such as Malmö Konsthall (2023), Kestner Gesellschaft, Hannover (2018), Kunstmuseum Basel (2017), Barbican Centre, London (2015), Swiss Institute, New York (2010), Palais de Tokyo, Paris (2008). His two solo exhibitions at the Kunstmuseum St.Gallen (1993/2014) achieved the highest audience records ever.
