Tulsa, Oklahoma – On this edition of StudioTulsa, we remember Wilma Mankiller, the former Principal Chief of the Cherokee Nation, who died yesterday at her home near Tahlequah after a battle with pancreatic cancer. Mankiller served as Principal Chief from late 1985 until 1995, when she retired from public office. (Mankiller was the first female Chief of the Cherokees, and one of the few women ever to lead a Native American tribe.) Among many other honors, she was awarded the Presidential Medal of Freedom by President Bill Clinton in 1998. In the fall of 1993, she published her autobiography, "Mankiller: A Chief and Her People" (St. Martin's Press) --- and shortly after this book first appeared, she came on our program to discuss it. We replay much of that conversation on today's show. Also on this edition of StudioTulsa, commentator Barry Friedman has a "Sleepless in Tulsa" anecdote that might sound familiar to anyone who's ever found himself driving around the city circa 5am.
