Replying to CR Johnson Biography/Autobiography??

So in english I have to pick an autobiography/biography and write about it and it has to be based on someone with courage. The first person that came to my mind was CR Johnson with him coming back from his major head trauma and all. I was wondering if there is a published biography or autobiography on his life? If so what is it called and where could I find it?

Help is much appreciated.

May he always Rest In Peace.
