Aby Moritz Warburg was a German art historian and cultural theorist who founded the Kulturwissenschaftliche Bibliothek Warburg, a private library, which was later moved to the Warburg Institute, London. At the heart of his research was the legacy of the classical world, and the transmission of classical representation, in the most varied areas of Western culture through to the Renaissance.

The Warburg Institute is a research institution associated with the University of London in central London, England. A member of the School of Advanced Study, its focus is the study of cultural history and the role of images in culture – cross-disciplinary and global. It is concerned with the histories of art and science, and their relationship with superstition, magic, and popular beliefs.
