Lisson Gallery has announced Lost and Found, a major survey of Susan Hiller's work opening at Zachęta – National Gallery of Art in Warsaw on 29 October 2026, running until 31 January 2027. The first institutional survey of her work in Poland, it spans five galleries and gathers five landmark bodies of work tracing her five-decade engagement with language, memory, perception, belief and imagination.

The presentation opens with Hiller's career-spanning investigation of anonymous British 'rough sea' postcards, from Addenda to Dedicated to the Unknown Artists (1976) through On the Edge (2015) — the collecting project behind Dedicated to the Unknown Artists (1972–76), one of the best-known British conceptual works of its period. Four major installations follow: Wild Talents (1997), a multichannel video originally commissioned by Warsaw's Foksal Gallery; J. Street Project (2003), a photographic record of German street signs bearing the prefix 'Juden'; Lost and Found (2016), an audiovisual work built from recordings in extinct, endangered and revived languages; and Die Gedanken sind frei (2011), an interactive installation of one hundred songs on justice, resistance, displacement and freedom.

Across video, photography, painting, sound and installation, Hiller transformed found and overlooked materials into investigations of the beliefs, assumptions and contradictions embedded in everyday life. Her approach to collecting and classification revealed latent connections between seemingly unrelated objects and experiences, renewing attention to the boundary between the familiar and the unknown. For five decades she explored what she called the fluid interrelation between the rational and the irrational — unstable zones where the liminal, the invisible and the unconscious hold sway.

Born in Tallahassee, Florida, in 1940 and based in London from the early 1960s until her death in 2019, Hiller has been the subject of a rolling sequence of posthumous surveys, including presentations at Culturgest in Lisbon and the Kunsthaus Biel in 2025 and the Museo Helga de Alvear in Cáceres in 2024. The Warsaw opening coincides with Bad Dreams at the KW Institute for Contemporary Art in Berlin, the first survey of her work in the German capital — a measure of how her standing has grown since her death.
