And what the heck is a Kiwanis anyway? Kiwanis International was founded in 1915 by businessmen in Detroit who originally called themselves the “Supreme Lodge Benevolent Order of Brothers” before quickly changing the name to “Kiwanis” after’s an American Indian expression “nunc kee-wanis,” for “we trade.” The organization then shifted their emphasis from fostering business contacts to being dedicated to helping children.
