Professor Mothersill died earlier this week, though I have not yet been able to locate any on-line information or memorial notices.  She was Professor Emerita at Barnard College, and was, of course, well-known for her many contributions to aesthetics.  I hope to post more information soon.

UPDATE:  A very lovely memorial notice by a former student at the American Society of Aesthetics website.  (Jackie Taylor, a philosopher at the University of San Francisco, writes that the author of this memorial, Linda Nochlin, is "the Lila Acheson Wallace Professor of Modern Art at NYU’s Institute of Fine Arts" and also "the author of the classic essay, ‘Why Have There Been No Great Women Artists?’"  My thanks to Professor Taylor for that additional information.)

ANOTHER:  A memorial notice from the Hume Society.
