In the James E. Grosjean Room of the Allen County Museum in Lima, Ohio, the docent flips a switch, the lights go out, and a filmstrip narration starts: light glows through stained glass, a dove crosses the scene, and the giraffes join the procession into the ark. Grosjean — undertaker, shoe salesman, inventor — built it in 1901; the Pan-American Exposition turned it down, and it went on to fill windows at Marshall Field’s and Macy’s.
