United States Marine Hospital (Cincinnati)

The United States Marine Hospital in Cincinnati refers to two different buildings that were part of the U.S. Marine Hospital system. The first building, completed in 1860, was never used as a Marine Hospital. Instead, it served as a military hospital during the American Civil War and was later sold to become Good Samaritan Hospital. The second building, a former mansion, operated as a Marine Hospital from 1882 to 1905. It was then repurposed as a water pollution field station and eventually became the primary environmental health research program of the U.S. Public Health Service, known today as the Andrew W. Breidenbach Environmental Research Center.

The first hospital, located at Sixth and Lock Streets near Mount Adams, was taken over by the Department of War during the Civil War and used as a military hospital. After the war, it was purchased by banker Joseph C. Butler and donated to the Sisters of Charity to establish Good Samaritan Hospital. The Sisters of Charity occupied the building until 1915 when they moved to a new location in the Clifton neighborhood.

The building was later sold and converted into apartments in 1924. Today, it no longer exists. The second building, a former mansion, operated as a Marine Hospital from 1882 to 1905. It was then repurposed as a water pollution field station and eventually became the primary environmental health research program of the U.S. Public Health Service, known today as the Andrew W. Breidenbach Environmental Research Center.
