"Victor Ernest Shelford (September 22, 1877 \u2013 December 27, 1968) was an American zoologist and animal ecologist who helped to establish ecology as a distinct field of study. Shelford's early visits to Volo Bog in Northern Illinois helped establish its ecological significance. Volo Bog became the first purchase of the Illinois Nature Conservancy, with the help of the fund-raising efforts of Cyrus Mark, the first president of the Illinois Nature Conservancy."@en . .
