Pittsburgh United States Marine Hospital

The Pittsburgh United States Marine Hospital is a brick structure built in Classical Revival style with wings extending symmetrically from a central entry. The building contains multiple stories with organized layouts designed for medical care and research operations.

Construction took place in 1909 on the site of a former military arsenal and served merchant sailors and maritime workers. The facility closed its marine operations in 1949 and transitioned to other medical uses.

The building served as a hub for medical professionals seeking to understand workplace health hazards through systematic study. It represented a shift in how the medical community approached occupational safety during a formative period for public health.

The building now operates as the Frank B. Clack Health Center and serves as headquarters for the Allegheny County Health Department. Access to the interior may be limited since it remains an active government facility with ongoing operations.

After its conversion from marine services, the facility operated a research-based nursery school led by a pioneering pediatrician during the 1950s. This experimental program explored new approaches to early childhood education and child development.
