Contrary Warrior: The Life and Times of Adam Fortunate Eagle
Eventually he becomes one of the principle architects of the American Indian takeover of Alcatraz Island in 1969--an action that brings about social change. Because of this the government declares him an "enemy of the state" and he loses his business and virtually everything he owns. Forced to go back to the reservation, he hones his skills as a ceremonial pipe maker, sculptor, and author and continues his calling as a ceremonial leader and statesman for his people. Vine Deloria, Jr., author of Custer Died For Your Sins wrote, "Fortunate Eagle is one of the most outstanding Indian leaders of this generation."
Unfortunately, he's not a captivating speaker. And other than Alcatraz, he hasn't had a lot of remarkable experiences. I'd say only aficionados will find his life interesting--not the general public.
