Step-by-step explanation:
Lillian Wald, a social reformer known for her contributions to public health and the welfare of children, was instrumental in the advancement of progressive social reforms in the early 20th century. As a key figure in the settlement house movement, Wald founded the Henry Street Settlement in New York in 1893.
The settlement house provided vital services such as child daycare, evening classes, libraries, gym facilities, and free health care, significantly aiding the working class, especially women and children.
Throughout her career, Wald collaborated with other reformers, such as Florence Kelley and Jane Addams, to advocate for changes that would lead to improvements in public health, housing, and labor laws, including the formation of the National Child Labor Committee (NCLC) and support for the creation of the U.S. Children's Bureau in 1912.
