All of us are many different people over time. We have our childhood selves, people that we remember, but they're very different to our adult selves and the way that we create our own naratives is not that dissimilar, I think, to how a biographer structures their narrative of a life.

We're all story-telling creatures, and also I think that's the point about biography because the life is exemplary.

People don't give up power and privilege out of the goodness of their hearts.

For me the fascination with biography is the life of the individual in the context of history.

Before my book, the most common assessment of Eleanor Marx is "Yes, she's great but basically she's in the shadow of her father." Absolute bollocks. She fought him, she resisted, and she was not a kind of trocadateur of his ideas.

Eleanor Marx was her father's first biographer. All subsequent biographies of Karl Marx, and most of Engels, draw on her work as their primary sources for the family history, often without knowing it. I think if she'd been a son, she would have been referenced more.
