Martha Beatrice Potter Webb (22 January 1858 - 30 April 1943) was an English socialist, economist and reformer.

Beatrice Webb was born in Gloucester, the granddaughter of a Radical MP, Richard Potter. In 1882, she had a relationship with Radical politician Joseph Chamberlain, by then a Cabinet minister. This was a failure, and in 1890 she was introduced to Sidney Webb, whose help she sought in research she was carrying out for her cousin, Charles Booth, whose Life and Labour of the People of London categorised the poorest into class A: "Vicious: borderline semi criminal" or class B "Casual earnings, very poor. The labourers do not get as much as three days work a week, but it is doubtful if many could or would work full time for long together if they had the opportunity". Marrying Sidney in 1892, the two remained together. Beatrice was an active partner in all Sidney's political and professional activities, including the organisation of the Fabian Society and the establishment of the London School of Economics. She co-authored books such as the History of Trade Unionism (1894), and was co-founder of the New Statesman magazine (1913).

My Apprenticeship has long been cited as an important and fascinating source for students of social attitudes and conditions in late Victorian Britain, and this new paperback edition makes it once more generally available. Beatrice Webb, the eighth of the nine daughters of the railway magnate Richard Potter, was an exceptionally able person, with a zest for observation, a knack for pointed comment, and a habit of self-examination – all of which gifts she put to good account in the private diary she kept all her life and in this brilliant volume of autobiography which she based on that diary. It tells the story of a craft and a creed, of a withdrawn but talented girl, growing up in a prosperous household, who turned to social investigation and social reform, moving between the two starkly contrasted worlds of West End smart society and East End squalor. She served a hard apprenticeship, as a woman as well as a professional worker, and in a new introduction to this edition Norman MacKenzie describes the severe personal stresses which lay behind her life of dedication to social improvement, particularly her frustrated passion for Joseph Chamberlain and the troubled courtship which preceded her marriage to Sidney Webb. This volume ends on the eve of that marriage, when she was about to begin her famous and astonishingly productive collaboration with her husband. As historians, publicists and Fabian politicians the Webbs were pioneers of the modern age. The ensuring volume, which chronicles their mature career and was appropriately titled Our Partnership, is also published by the Cambridge University Press in collaboration with the London School of Economics and Political Science.
