When and why did Isle Royale become a national park?

Question

Please help me.

Answer 1

Isle Royale National Park was established on 03 April 1940 by President Franklin D. Roosevelt.

"While fishing, tourism, and shipping still prospered in the 1920's, a Detroit News editor, Albert Stoll, Jr., and others, began a movement calling for the creation of Isle Royale National Park. Roughly half of the main island's area was quickly pledged to the Park Service, but fishing families and logging and mining interests had yet to be convinced of the value of creating a National Park.

Herbert Hoover signed legislation calling for the creation of a National Park at the start of the Great Depression, and FDR created the Civilian Conservation Corps, with camps established at what is now called Daisy Farm, Windigo, and Siskiwit Bay. ..."
