The United States Department of Health and Human Services (HHS), also known as the Health Department, is a cabinet-level department of the U.S. federal government with the goal of protecting the health of all Americans and providing essential human services. Its motto is "Improving the health, safety, and well-being of America". Before the separate federal Department of Education was created in 1979, it was called the Department of Health, Education, and Welfare (HEW). 

The Federal Security Agency (FSA) was established on July 1, 1939, under the Reorganization Act of 1939, P.L. 76-19. The objective was to bring together in one agency all federal programs in the fields of health, education, and social security. The first Federal Security Administrator was Paul V. McNutt. 

The new agency originally consisted of the following major components: (1) Office of the Administrator, (2) Public Health Service (PHS), (3) Office of Education, (4) Civilian Conservation Corps, and (5) Social Security Board. 



Organizational Changes 

When the war ended, President Truman moved to "strengthen the arm of the federal government for better integration of services in the fields of health, education, and welfare." 

Unlike statutes authorizing the creation of other executive departments, the contents of Reorganization Plan No. 1 of 1953 were never properly codified within the United States Code, although Congress did codify a later statute ratifying the Plan. Today, the Plan is included as an appendix to Title 5 of the United States Code. The result is that HHS is the only executive department whose statutory foundation today rests on a confusing combination of several codified and uncodified statutes.
