Alberto Giacommetti is one of my favorite sculptors. The Museum of Modern Art has an exposition of his work (Flash warning) right now and has some of it online.

Without being a scholar or having officially studied him, his figures speak existentialism to me - we live, as we dream, alone. We are separated from one another. We are fragile, negligible objects in this world. Don't miss his 'City Square'.

On a totally different scale, I really like Paul Granlund's sculptures. The largest concentration appear at Gustavus-Adolphus College, where Granlund was sculptor in residence and still has his studio. His Dancing Francis is very famous, and we now have a copy of it at Wartburg College, where Christine and I attended.
