Well, when Eleanor Roosevelt's mother dies, she goes to live with her Grandmother Hall. And her Grandmother Hall is in mourning. She's in widow's weeds. She's in her 50s, but appears very old. And she's exhausted from raising rather out-of-control children. Her favorite daughter, Anna, has died (Eleanor's mother), and she has living at home two other sons, Vallie and Eddie. And they are incredible sportsmen, incredible drinkers, out-of-control alcoholics.

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.

So she [Eleanor Roosevelt] is an amazing First Lady. What other First Lady in U.S. history has ever written a book to criticize her husband's policies?

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.

I think that, very often there's a pain that's just too painful to touch. You'll break apart. And I think her mother's death and disappearance and abandonment was something she just never could deal with. Eleanor Roosevelt, when she's really very unwell in 1936, she takes to her bed. She has a mysterious flu.

Eleanor Roosevelt fights for an anti-lynch law with the NAACP, with Walter White and Mary McLeod Bethune. And she begs FDR to say one word, say one word to prevent a filibuster or to end a filibuster. From '34 to '35 to '36 to '37 to '38, it comes up again and again, and FDR doesn't say one word. And the correspondence between them that we have, I mean, she says, "I cannot believe you're not going to say one word." And she writes to Walter White, "I've asked FDR to say one word. Perhaps he will." But he doesn't. And these become very bitter disagreements.
