John Kaldor AM is a dedicated collector, patron and supporter of contemporary art. He has been collecting and commissioning art since the late 1950s and since 1969 has shared his love of art with the Australian public through his series of art projects.

Kaldor has brought the most innovative and groundbreaking art to Australia for over 45 years through what is now the not-for-profit organisation Kaldor Public Art Projects, listed since 2004 on the national Register of Cultural Organisations. Kaldor has participated on the boards and international councils of many art organisations over the years, including P.S.1 in New York, the Tate Modern, London, the Biennale of Sydney, and as chair of the Museum of Contemporary Art, Sydney. He was selected as commissioner for the Australian Pavilion at the 51st Venice Biennale in 2005 and again for the 52nd Venice Biennale in 2007. Kaldor was a founding member of the board of the Power Institute of Contemporary Art, a trustee of the Art Gallery of New South Wales, Sydney, and is currently on the International Council of the Museum of Modern Art, New York.

In 2011, Kaldor gifted his private collection to the Art Gallery of New South Wales, bringing these works into public view. He also continues to extend his contribution to public art and education as Director of Kaldor Public Art Projects.
