Steve Kulchek’s old basketball ankle injury kicked in so he went to Sports Medicine at the Beth Israel Mecial Center on 14th Street and Union Square East. He brightened up when he saw the wing was named after Louis Armstrong, one of his favorite trumpeters. I asked him why a hospital wing would be named after a musician. It’s an American curiosity, isn’t it? Is it our love of celebrities? We’re ahistorical but we need famous people. Can you imagine a photo of Lafayette eliciting the same response as Louis Armstrong? Never. Lafayette is dead and foreign. Besides, few people have heard of him. How about the picture of a saint? Can you imagine Saint Sabastian complete with arrows hanging in the medical center’s atrium?
