Sister Carmela Hanggi, principal of Cathedral School in St. Paul and a member of the Sisters of St. Joseph of Carondelet, founds the School Safety Patrol in Minnesota, which becomes an international model for parochial and public institutions. At first a school-police program for boys who serve as guards helping fellow elementary-school students cross busy streets, Sister Carmela's enterprise would inspire the organization of numerous programs that now include girl guards and bus patrols.
