The Collection of Thomas and Doris Ammann is dedicated to the breadth and scope of the trove formed by two of the world’s most respected art dealers. As co-founders of Thomas Ammann Fine Art, the Swiss siblings became indisputable taste leaders of the art world, renowned for their expertise in the market. Aside from their art dealings, the Ammanns also built a monumental collection of their own, of post-war and contemporary art. It includes significant work by Andy Warhol, Cy Twombly, Robert Ryman, Martin Kippenberger and Sigmar Polke — as well as more hidden talents, such as Martin Disler, Ann Craven and Klaudia Schifferle.

Debuting in the May 2022 season, their collection continues to be offered in a series of sales. In March 2023, Christie’s presents the first dedicated online auction of the collection. All of the Foundation’s proceeds from the sales will benefit the Thomas and Doris Ammann Foundation, a newly established organisation dedicated to improving the lives of children worldwide.

Works from The Collection of Thomas and Doris Ammann will be offered in the upcoming 20th/21st Century Evening Sale on 28 June and Post-War and Contemporary Art Day Sale on 29 June, in London, as well as in First Open: Post-War and Contemporary Art Online from 21 June to 5 July.
