By the time Kirkeby completed a masters degree in arctic geology at the University of Copenhagen in 1964, he was already part of the important experimental art school "eks-skolen." His interest in geology and other aspects of the natural world was fundamental to and characteristic of his art. Kirkeby worked as a painter, sculptor, writer, and printmaker.
Kirkeby taught as a professor at the Karlsruhe Institue of Tecnology(1978–89) and at Städelschule in Frankfurt am Main (1989–2000). Per Kirkeby was a member of the Danish Academy from 1982. In 1997 he became a Knight of the Order of Dannebrog..
His works have been exhibited worldwide and are represented in many important public collections, e.g. Tate London, Metropolitan Museum of Art, New York, Museum of Modern Art, New York and Centre Pompidou in Paris. Wikipedia
