This article explores one of the classic questions in the history of old age: what happened to the status of the elderly in the nineteenth century? How do we explain the emergence of the modern notion of an old age defined by ‘declines’ of every sort (cognitive, physical, financial)? The article focuses on Germany, then and now a global leader on this issue, and it focuses on women, whose ageing was more widely discussed than that of men. It shows that the great nineteenth‐century debate about the elderly was not about industrialisation, labour, health or social policy. It was a debate about time. The cultural understanding of the elderly changed because the culture of temporality did. The focus on futurity and the youth around 1900 is well known, as modern Germany became convulsed with imperial fantasies and electric urban life. This had, it turns out, negative repercussions for older Germans. No longer the accretions of a long past of wisdom and experience, they were identified instead with their short future of corporeal decline and death. The social attitude towards older people is therefore related to the broader social attitude towards time, history and change: a finding that might apply in other times and places, including our own.
