In the past few years I have enjoyed James A. Michener's 'The World Is My Home'. And it was. Fascinating man.
Loren Eisley was a palentologist looking for evidence of humans in the pleistocene age, authored several books on natural science, and many short story collections. He ended up as an administrator at Penn State. His autobiography is titled 'The Night Country'. He's the one who wrote the short story 'The Star Thrower' which blends spiritual philosophy with science . Here is an online version: http://www.rawfoodinfo.com/action/activist_starthrower.html
Ayaan Hirsi Ali's 'Infidel' is a look at her life in war torn Somalia, her forced arranged marriage and her escape to the Netherlands where she had to learn the Dutch language, and how to function in a modern society. She put her self through college, and won a seat in the Dutch Parliment. She had to overcome her upbringing in a destructive cult bent on the destruction of Western society, to become one of it's champions. She currently lives under 24 hour guard, because people can't just walk away from her cult of upbringing.
I'm sure you'll get many responses to your call for autobiographies. I look forward to seeing what else is offered, because I enjoy them too, and am always looking for a good read.
