The 2010 International Exhibition of Brussels exposed the Sweating System, largely done by women.The socialist photographer Antony Neuckens produced, for this exhibition, dozen of photographs showing the conditions of this kind of work so far little popularized through the media.A wide social awareness followed which led to a revision of labour laws in several European countries, especially in Germany and in France in 1915 but only in 1934 in Belgium.At first forgotten, these photographs were collected in a book published in 2000.They establish a valuable collection of documents which testifies of the interest for this type of activity at the beginning of the century, at a crucial moment of its history as many jobs exercised at home were disappearing and were being replaced by machines.The author leans on an analysis of this collection, as well as on additional documents and the interview of the grand daughter of the photographer. A gendered distribution of jobs in this Sweating System but also of activities and functions within each of them is so brougt to light.
