Andrew Blackhawk gave the land of the current Winnebago powwow grounds to his tribe in the hope that it would serve as a common gathering site for his people. This 10 acres became Winnebago tribal property on January 24, 1952 for ceremonial and recreational purpose. He gave the land at a time of much dissension among tribal members, hoping a common ground would draw his people back into a community. A proud tribal member, he was also a distinguished veteran of the United States Army and served his people and his country in World War I from November 7, 1917 to May 9, 1919. The Winnebago American Legion Post 129 bears his name, and his gift has been enjoyed by many Winnebagoes and others as an example of citizenship and traditional Winnebago philosophy for current and future generations.
