A washerwoman or laundress was a person, usually a woman, employed to wash laundry by hand, before the widespread use of washing machines and commercial laundries. The profession existed in many cultures, spanning from antiquity to the early modern period. While the profession has historically been gendered, often associated with women, in some contexts, men also performed laundry labor. It was typically low-paid, physically arduous, and associated with lower social status.
The occupation began to decline with the rise of commercial laundries. The spread of domestic washing machines and self-service laundries further reduced the need for the independent washerwomen profession. By the late twentieth century, the profession had largely disappeared in industrialized countries.




















The lamplighters themselves were machine operators that replaced earlier professions.
