Biography of famous woman

I asked my girls to pick out a biography of a famous woman, read it, and write a little report about her. To give them an idea, I said, "Maybe someone like Helen Keller?" One daughter came back with a biography of Eleanor Roosevelt. Perfect. Just the kind of woman I was thinking about. Then the other daughter arrived. She had been looking for a biography of Mia Hamm, the great American soccer player. That would have been fine, except she couldn't find a Mia Hamm book, so she came back with a different biography--of Britney Spears! I about dropped my stack of books on the floor in horror! "You said pick a book about any woman," she said, quoting me in that confident manner she uses when precision memory proves her right. "And she's a famous woman," she concluded, plopping the book on top of her stack.

"I'm not sure we can call her a woman," I muttered. Drat. My face contorted into an inexplicable form, scrunching into a kind of smirk, I suppose, as I tried to express something less than positive about her selection without insulting my daughter. I was unsure what to do. We had to leave, she had a book, she followed my vague, general rules, and evidently I haven't expressed sufficient disrespect for Spears. I don't want to read a report about her, so I guess I'll just make another trip to the library.

And next time, my assignment will be much more specific, with a list of famous women to choose from. Who would you include?
