Aby Moritz Warburg, better known as Aby Warburg, (June 13, 1866 – October 26, 1929) was a German art historian and cultural theorist who founded the Kulturwissenschaftliche Bibliothek Warburg (Library for Cultural Studies), 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.
