Human beings have always worried about ageing, with special worry reserved for premature ageing. Consequently, we have tried numerous different methods to try and achieve rejuvenation - a state of renewed youth or the appearance of youth. The everyday methods with which we are perhaps most familiar - skin care products, dietary and exercise regimes - have long histories but were transformed in the decades following the First World War, when a wealth of scientific research and new anti-ageing products appeared to promise the ability to prolong youthfulness, fertility and vitality. This Fellowship sets out to examine the impact of the most widespread methods of rejuvenation - injection and application of hormones, using electricity on the body, skincare products, specific diets and exercise regimes - on post-WWI Britain. We already know from previous historical work that the unique socio-political context of interwar Germany precipitated the rise of eugenic ideals about race and biology, as well as beauty and ugliness, whilst at the same time the rising consumer-culture context of the United States enthusiastically embraced technological and scientific developments linked to human ageing. However, Britain in this period has remained largely unstudied, and consequently we risk overstating the significance of developments elsewhere. Concerns about the overall fitness (and fertility) of the population were increased by Britain's participation in the two World Wars, and it is clear that the perceived need for rejuvenation of both individuals and society became a topic of intense debate both in medical and scientific circles and in the wider public sphere. Especially prior to the NHS, manufacturers and entrepreneurs attempted to exploit this fascination, and they claimed that a number of existing therapies had rejuvenating properties, as well as trying to introduce new devices and products. The domestication of electrical lighting and the increasingly wide reach of cinema and photography also placed added pressure on the British public, and particularly women, to look at their best. The Fellowship will explore why rejuvenation was such a prominent matter of public interest in this period, and it will show in what ways the methods used to slow, stop or even reverse ageing helped to define some of the most fundamental elements of what it means to be human. The principal goals are to (i) explain the diversity of approaches to rejuvenation, (ii) examine the different advertising and marketing strategies and their relationship with contemporary scientific perspectives on ageing, and (iii) uncover how everyday habits were changed by anti-ageing products, procedures and lifestyles. Allied to this, the Fellowship will explain how manufacturers of rejuvenation preparations and devices attempted to convince British publics of the efficacy of their products, and show to what extent the target audiences of these products were persuaded by such claims. The Fellowship seeks to explain how and why this period in Britain became such a fruitful environment for different rejuvenation strategies. Drawing on a wide range of archival materials, including the papers of manufacturers and retailers of rejuvenation-related products (such as Boots, Pond's and Elizabeth Arden), newspaper and periodical sources, objects, specialist scientific and medical texts, personal accounts and fictional representations of rejuvenation, the project will link together histories of the body, ageing, the limits of biomedical explanation, everyday medical practice, the impact of global conflict on health and wellbeing, and the medical marketplace, amongst other themes. The Fellowship will consequently deepen our understanding of the historical body and the human condition by demonstrating that ageing and rejuvenation were intimately connected with a wide range of medial, social, cultural and economic factors, including beauty, gender, class, race, warfare, and eugenics.
