By 1938, Eleanor Roosevelt was so angry at FDR's policies, she writes a book called This Troubled World. And it is actually a point-by-point rebuttal of her husband's foreign policy. We need collective security. We need a World Court. We need something like the League of Nations. We need to work together to fight fascism. We need embargoes against aggressor nations, and we need to name aggressor nations. All of which is a direct contradiction of FDR's policies.

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.

She really is a completely different First Lady. Eleanor Roosevelt was not going to suffer and withdraw in the White House. And I think he's a very different President. He does not want his wife to suffer and withdraw in the White House. And they really are partners. They're partners in a big house where there are two separate courts, and they both know they have two separate courts. But these are courts that are allied in purpose, united in vision.

I think that Eleanor Roosevelt really learned about the limits of power and influence from Arthurdale. She could not make some things happen. And she particularly learned that she could not, just because she was nominally in charge, she could not change people's hearts and minds; that a very long process of education would result before race was on the national agenda. And it really did move her into the racial justice arena with both feet. She came out fighting.

It's interesting to me that really one of the first things she [Eleanor Roosevelt]did as First Lady was to collect her father's letters and publish a book called The Letters of My Father, essentially, hunting big game, The Letters of Elliott Roosevelt. And it really was an act of redemption, really one of her first acts of redemption as she entered the White House. She was going to redeem her father's honor. And publishing his letters, reconnecting with her childhood really fortified her to go on into the difficult White House years.

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 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.
