SUMMARY & BIO There is a fascinating and often bizarre world of early 20th century pills, potions and powders made from radioactive materials. In this illustrated talk Lucy will explore how both uranium and radium were incorporated into pharmaceutical preparations from tonics to face creams in the UK, the US and France and  explain how these radioactive substances were marketed to the masses as essential for health. The talk will conclude with a reflection on why uranium and radium fell out of favour, shedding light on the shifting attitudes toward safety, science, and regulation. BIO: Specialising in the late 19th and early 20th century Lucy Jane Santos is a freelance historian and consultant uncovering the hidden stories of how science and technology have transformed daily life, especially when it comes to innovations in beauty practices.​ ​
