In A History of the World in 21 Women, Jenni Murray celebrates great women from around the world – rescuing some from obscurity and shining a new light on familiar names. Breaking the mould in art, science, journalism and politics, each of these women fought, in her own way, for change. From Joan of Arc to Madonna and all points in between,  this is a personal, lively and unique history from the much – loved presenter of Women’s Hour.
