History
The Nature Conservancy developed out of a scholarly organization initially known as the Ecological Society of America (ESA). The ESA was founded in 1915, and later formed a Committee on Preservation of Natural Areas for Ecological Study, headed by Victor Shelford. The primary aim of Shelford was to find areas of land that would be beneficial for long-term research. By the 1930s, Shelford and his colleagues such as Aldo Leopold increasingly sought to advocate for conservation. The divide in viewpoints regarding scholarship or advocacy led the Society to dissolve the committee and in 1946, Shelford and his colleagues formed the Ecologists' Union. The latter group eventually took the name "The Nature Conservancy", in emulation of the British agency of that name, which pursued a mission of conserving open space and wildlife preserves. The Nature Conservancy was incorporated in the United States as a non-profit organization on October 22, 1951.

Why this record matters
