Blue Cross/Build Shield Building, 1957

A collector’s item, this building is a singularly studious work in which you can find comment on the condition of modern architecture as it entered the sixties. The best architects were confidently searching for forms of expression that would be rich in visual texture and appropriately scaled, but rooted still in the basic elements of construction. The building is structure embodied, structure shaped to give it measurable, discernible form—to be seen in sunlight and to be wondered about. It comes from a period when architects still thought they could control the building process, not just clothe it. And they knew their heritage.... For all that, like too many scholars, the building earns more respect than affection.
