Assume or pretend you are a recent appointee to a National Organization for Human Services committee tasked with writing a new reference book for Human Services. The book must include several chapters on historical pioneers in Human Services and is titled History and Foundations of Human Services in the Nineteenth and Twentieth Centuries. Historic pioneers are those persons who helped create a field of study or made significant advancements in solving a social problem or improving social welfare through direct service or political advocacy. The editors of the book have asked all authors to nominate a person who made extraordinary contributions to the field of human services (or social work) in the nineteenth or twentieth century. An external committee will vote on the nominations, and those authors whose nominations receive the most votes will write a chapter on their nominee for inclusion in the book.
