Hugh Davis and the 1972 anniversary gift
Hugh Davis was a Tulsa Zoo employee for nearly four decades — joining as a reptile keeper in the 1930s and rising to become the zoo's director through the 1950s and 1960s. He was nationally respected in the herpetology field and authored multiple academic papers on snake biology and reptile behavior. His wife Zelta worked alongside him at the zoo, eventually becoming the zoo's curator of reptiles and amphibians. They married in 1938 and bought the Catoosa property in 1953 as a private weekend retreat where they could keep their personal animal collection.
The property became Nature's Acres in the late 1950s — initially just a small ADA-style alligator and snake collection that they opened to the public on weekends, but eventually a working roadside zoo with a swimming hole, picnic grounds, and exhibits. By the late 1960s, Nature's Acres was attracting hundreds of visitors per weekend and the swimming hole had become the unofficial summer gathering spot for Catoosa-area families.
Hugh began construction on the Blue Whale in 1970 with the project planned as a 34th-anniversary gift for Zelta. He worked entirely by himself using welded steel pipe for the internal armature and concrete sculpted by hand over the framework. The construction took roughly two years — Hugh worked nights and weekends after his Tulsa Zoo shifts — and the whale was completed in time for their 1972 anniversary. The unveiling involved a small family celebration with their three children and grandchildren; the moment when Zelta saw the whale for the first time is preserved in a series of family photographs that are displayed at the on-site gift shop today.
