“To identify the mot important artists, our sample includes all painters born from 1830 through 1900, who were natives of France or spent most of their careers there, and who had at least one painting reproduced in at least three of five designated art history textbooks.” Galeson, D.W. and Weinberg, B.A. “Creating modern art …” American Economic Review, 91 (4) 2001.
