The Blue Whale was built by Hugh S. Davis, Boy Scout, photographer, zoologist, lecturer, father of two, grandfather of four, great-grandfather of nine and friend of many...Hugh always had a “project” in the making…whether it was building furniture, creating an alligator ranch or constructing an ark, he was always busy. After his retirement from the Tulsa Zoo, he devoted all of his time to developing facilities to educate people about nature... In the late 1960’s at the age of 60, Hugh began to doodle pictures of a “fish” that he wanted to build at the pond. From that fish evolved a whale – larger and larger he grew from sketches on napkins to drawings on oversized sheets of paper...To accomplish his plan, he needed help fashioning the iron framework – the skeleton of the whale. For this task he called on his dear friend, Harold Thomas, a welder, to weld the 20-foot-tall, 80-foot-long structure...It took two years, 1970-1972, to build the whale. According to Hugh’s notes, he worked 2,920 hours applying the cement which he hand mixed and applied one five-gallon bucket at a time. (Belt, History, full citation below).
