The Museum was founded in 1926 during the United States Sesquicentennial Exposition. The park, then called League Island Park, served as the primary venue for the city-wide celebrations.  Amandus Johnson, a Swedish-American historian and the Museum’s founder, envisioned the Museum as a place to preserve and promote Swedish and Swedish-American heritage, history and culture.  Each gallery was designed to present its own miniature museum concentrating on a specific area of Swedish accomplishment. The Museum’s grand opening in 1938 marked the 300th anniversary of the New Sweden Colony in the Delaware Valley.

Civil War Collection

John Ericsson Papers and Collections                    
The life and work of inventor John Ericsson (1803-1889) are chronicled in over 3,000 items spanning 1839-1889. Ericsson is best remembered for changing the course of naval history with the invention of the screw propeller and design of a propeller-driven ship, the ironclad Monitor, which fought the Confederate Virginia (Merrimac) during the Civil War.  Included in ASHM collection are Ericsson’s correspondence with professional and business associates, drawings and descriptions of inventions, articles by him for leading scientific journals, records of awards, and documentation from his legal battles over patents and contracts.

Finding aid and microfilm access is available, as well as access to the collection via research appointment with the curator.
