During the inter-war years women found employment for the first time in some of Britain's industrial laboratories, most of them concentrated in the food, pharmaceuticals, cosmetics, textiles and photographic industries. Drawing on a range of sources, including company archives and the technical press, this paper examines the emergence of these new positions for women and considers their workplace experiences, looking both at women with higher-level qualifications and at those who worked as laboratory assistants. It argues that although the entry of women into industrial chemistry represented an extension of their opportunities for scientific work, they tended to be employed as ‘women chemists’ to undertake routine tasks seen as especially suited to feminine skills and expertise and to have few opportunities for promotion. Their presence also appears to have changed the nature of men's work, helping to ensure that men could continue to be offered more challenging work and positions which retained the possibility of career advancement.
