An important and forceful left-wing intellectual (a shaper both of the Fabian Society and of the Labour Party), Beatrice Webb wrote at the end of the nineteenth century and in the early twentieth century. Her subjects were social issues: for instance, unemployment, and the development of the co-operative movement and of trade unions. She was also (and from the same public-spirited motives) remarkable as a diarist and autobiographer. Almost all her writing on public topics (nearly forty publications, including eighteen monographs) was done in collaboration with her husband, Sidney Webb. So thoroughly are they thought of as one mind that joint biographies of them are more common than individual ones.
