hospitals and the National Leprosarium operating. The system was abolished in 1981, with the last eight general hospitals transferred to other organizations, and the remaining functions of the Bureau of Medical Services merged into the present Bureau of Primary Health Care within the Health Resources and Services Administration (HRSA). PHS would however continue to operate the National Leprosarium until 1999. Other pre-1912 divisions of the Marine Hospital Service have descendants that operate to the present day: The Division of Domestic Quarantine became the Division of States Relations and then the Bureau of State Services in 1943. This bureau would eventually give rise to the modern Centers for Disease Control and Prevention (CDC), as well as the HRSA Bureau of Health Workforce and Healthcare Systems Bureau. The Division of Scientific Research became the National Institutes of Health. The Environmental Health Divisions (predecessor of the Environmental Protection Agency and FDA Center for Devices and Radiological Health), and the Division of Industrial Hygiene (predecessor of the National Institute for Occupational Safety and Health), were spun off from it in the mid-20th century. The Division of Foreign Quarantine eventually became the CDC Division of Global Migration and Quarantine. The Division of Sanitary Reports and Statistics was an ancestor of the CDC National Center for Health Statistics. Today, the records for these institutions sit in storage at the National Library of Medicine in Bethesda, Maryland and the National Archives in College Park, Maryland. Hospitals The hospitals themselves were, by the middle of the 19th century, fairly imposing and architecturally grand structures in many cases. As long as ample federal funding was available for their construction, these hospitals were impressive examples of government-provided health care. The hospitals of the early 20th century in major port cities such as New Orleans, San Francisco, and Savannah displayed ornate architectural detail and reflected many of the changes sweeping medicine at the time. In addition to the major hospitals, many lower-class hospitals and clinics existed.
