14831 Gentileschi           Discovered 1987 Jan. 22 by E. W. Elst at the European Southern Observatory.
Artemisia Gentileschi (1593-1652), the only daughter of the Italian painter Orazio Gentileschi, became famous herself through paintings such as "Self-Portrait as the Allegory of Painting" and frieze "Inclinazione". Her paintings of powerful women struggling against male dominance were not appreciated by the male aristocracy.
