The idea for the Rebild National Park Society began with a meeting of Ivar Kirkegaard of Racine, Wisconsin and some of his friends in the year 1905, but it was Max Henius of Chicago who brought the idea to fruition. The first celebration in Denmark of the American 4th of July took place at a meeting of Danish Americans in the city of Aarhus in 1909, but the first event to take place in the Rebild Hills didn’t occur until the year 1912, thus the year 2012 is the hundredth anniversary of that event as well as the beginning of the Rebild National Park Society. Henius’ book came to be published (in June, 1912) primarily because of that event, the first Rebild celebration, which was to take place later that year.
