Politics is not an isolated, individualist adventure. Women really need to emerge as a power to be the countervailing power to the men. And Eleanor Roosevelt's really the dynamo and the spearhead of that effort.

She writes that one of the moments that she felt most useful was when her mother had a headache, and she would stroke her head and rub her forehead. And I think Eleanor Roosevelt's entire life was dedicated to two things: (one) making it better for all people, people in trouble and in need, like her family.

I mean, if you pause over what it means at the age of 76 that Eleanor Roosevelt wrote, the happiest single day of her life was the day she made the first team at field hockey. Field hockey is a team sport. Field hockey is a knockabout - I mean, picture Allenswood, the swamps of north London. It's a messy sport. So she really enjoyed playing this rough-and-tumble sport in the mud of Allenswood, a team sport. And she was very competitive. And she loved being competitive, and she loved to win. And that, I think, was all of the things that Allenswood enabled.

Eleanor Roosevelt started off almost every early article she wrote, starting with, "My mother was the most beautiful woman I'd ever seen." And I think her life was a constant and continual and lifelong contrast with her mother.

And she [Eleanor Roosevelt]loves being a star. And she loves being a teacher and a leader and a mentor and a big friend. Also, she's tall. She's one of the tallest girls in the school. And she's an athlete. And she writes many years later, at the end of her life, she writes that the happiest day, the happiest single day of her life was the day that she made the first team at field hockey. And I have to say, as a biographer, that's the most important fact. I

And if you look at pictures of Eleanor between 1918 and 1921, she becomes anorexic. She really loses a tremendous amount of weight. That's when her teeth really go bad. It's a terrible, terrible time for her. And she has five children, ranging in age from three to 10. It's an emotionally terrible ordeal.

And in the same way, FDR's not much of a father. Although the children in all their memoirs really talk about what a fun-loving guy Dad was, and how brooding and unhappy Mom was. The children sort of blame it all on the mother. Well, this is kind of standard and typical, and aggrieved Eleanor Roosevelt that she was not a happier mother. She wanted to be a happier mother. And I must say, she was a happier grandmother.
