Primary archives do not record a founder or inaugural year for National Panda Day. The date circulates each March 16 through wildlife-conservation groups, and gained documented institutional pickup by 2022, when the Smithsonian's National Zoo timed the launch of its giant panda 50th-anniversary celebration to it.
How a bear became a brand
The turn came in 1961, when a new conservation group needed a face. The World Wildlife Fund built its logo around Chi-Chi, a giant panda then living at the London Zoo. Artist Gerald Watterson sketched her, and co-founder Sir Peter Scott drew the emblem.
The choice was deliberate. Scott wanted "an animal that is beautiful, is endangered, and one loved by many people," and one that read clearly in black and white "to save money on printing costs." The panda became shorthand for everything at risk in the natural world.
