Susan Hiller (born 1940) is an ex-anthropologist who first rose to prominence in the 1970s as a radical, feminist artist with a particular interest in the workings of the subconscious. This year, she’s the subject of a major retrospective at Tate Britain, while Timothy Taylor Gallery is exhibiting a selection of recent pieces – testimony to just how influential her work has become (although whether you think that influence a good or bad thing may depend on your view of contemporary art’s fixation on found objects, forgotten voices, and the process of its own creation). Time has dulled the originality of Hiller’s work while taking none of the edge off its self-important tone [1]; still, her argument for the validity of subconscious experience is as vehement and urgent today as it ever was.
