These are hallowed grounds in term of design. Harry Weese, Charles and Ray Eames, Harry Bertoia, Florence Knoll, Benjamin Baldwin, Ralph Rapson, Kevin Roche, Edmund Bacon and Eero Saarinen all went to Cranbrook.

There was a great Bertoia print and jewelry exhibition in the museum, but they didn't allow photography.
