Final answer:
Lillian Wald is credited with founding public health nursing and establishing the Henry Street Settlement and nursing health services in New York, which provided a variety of community services including public health care.
Step-by-step explanation:
Lillian Wald was a pioneering nurse and social reformer who led the early progressive reform movement in the United States. In 1893, she established the Henry Street Settlement in New York City. This settlement house provided a variety of services to the community, including healthcare, which was significant at the time since it was one of the first instances of organized public health services in the country. Wald's work was crucial in pioneering the field of public health nursing, and she was also influential in various social reforms, such as improved housing conditions, child labor laws, and workers' rights.
Her legacy extends beyond healthcare as it is also intertwined with the larger social work movement, playing a critical role in shaping health and welfare policies in the early 20th century. Other notable figures like Jane Addams, Florence Nightingale, and John Snow also made significant contributions to public health and social reforms but Lillian Wald was specifically associated with the Henry Street Settlement and the establishment of public health nursing in the United States.
