A longtime member of the Department of Philosophy (and the Philosophy-Neuroscience-Psychology Program) at Washington University, St. Louis, where he was emeritus, he was also an important Chair of the Department.  His philosophical work was in aesthetics and philosophy of cognitive science, and often their intersection.   The Wash U memorial notice is here.  Comments are open for remembrances from those who knew Professor Rollins or for those who wish to comment on the significance of his work.
