Messmore & Damon brought to life huge dinosaurs, tigers, mastodons, dragons, other monsters, and even cows. One of their creations was a life-sized (48 feet long, nine feet high, 4,000 pounds) mechanized reproduction of a dinosaur, Amphibious Dinosaur Brontosaurus (aka “Dolores” or “Dino”). It could laugh, breathe, roll its eyes, shake its head, and move its jaws. It was a must see. Created for the Century of Progress International Exhibition (1933-1934), “The World a Million Years Ago,” Dino was made of layers of chicken wire, canvas, rattan, papier-mâché, and paint. A human ran a complicated series of motors, chains, ball bearings, gears, cranks, counterweights, and universal joints that worked in concert to create a spectacular experience. The dinosaur was capable of moving its head in all directions and it had a moveable jaw. George Messmore’s 1933 patent (US Patent 1,898,587) stated “the jaw was intended to hold a dancer so that the dancer may be lifted up by the animal for entertaining purposes.” Dino hit the entertainment circuit after the Fair entertaining thousands at department stores and other venues. He even inspired an essay contest for youngsters who were asked, “What Would Happen if Dino Lived Today?”
