For three decades Calvin Tomkins has written about art for The New Yorker. The world he portrayed — through profiles of artists, architects and curators like Philip Johnson, John Cage, Merce Cunningham, Pontus Hulten, Walter Hopps, Renzo Piano, Robert Rauschenberg, Dia Art Foundation — was also the world of John and Dominique de Menil. Calvin Tomkins will recall that world in conversation with Menil director, Josef Helfenstein.
