Betsy Cadwaladyr travelled the world as a maid aboard ship before serving alongside Florence Nightingale in the Crimean War.
Betsy, born Elizabeth Davies, grew up in Bala, the daughter of a Methodist preacher. Yet she always longed to explore further afield, and left to enter domestic service in Liverpool at the age of 14. She then travelled the world, working as captain's maid and assistant, before settling in London to train as a nurse.
After reading about the plight of British soldiers in the Crimean War, who were dying of typhoid and wound infections, Betsy decided to join the military nursing service to take care of them. She worked alongside Florence Nightingale for a time, but did not like her imperious discipline.
Betsy moved to serve on the Balaclavan front, where she was famous for her disregard of red tape to ensure that supplies reached the wounded.
