A great artist and a good friend, Tim Rollins, died suddenly a week ago. Tributes to Tim, and his important work with the K.O.S. collective he founded, immediately appeared all over the arts press, and today the Times published a long obituary that appropriately honored his extraordinary career and personality. I had the privilege of getting to know Tim at WhiteBox, where in 2003 we showed his large-scale installation “War of the Worlds”, and where he showed up at just about every opening and event, in his signature black suit and cowboy hat. For several months I worked with him developing a book surveying the huge body of work he generated with K.O.S., a group of gifted but underprivileged student/collaborators to whom he was devoted, as they were to him. Sadly, that book never got published — it was presented to major publishers at a dip in his career — but, aside from MIT Press’s 2009 history of the group, no retrospective catalogue of Tim’s art has since emerged. I’m sitting on a pile of archival material that Tim provided me, and I’m thinking, since his star has risen in every sense, that it might now be time to pitch the proposal again. —John Isaacs
