One fellowship is awarded annually for 24 months. This fellowship is intended for the advancement and completion of a doctoral dissertation in a field through the 20th century other than European or American art or in cross-cultural studies involving at least one culture outside the European or American traditions. The Andrew W. Mellon Fellow is expected to spend the first year of the fellowship period in a specific city, locality, or region related to the dissertation. The second year is to be spent in residence at the Center to complete the dissertation.
