Roosevelt Island, the narrow strip of land in New York City's East River, has undergone several name changes reflecting its evolving history. Originally called Minnehanonck by the Lenape, it was later known as Manning's Island and then Blackwell's Island after its private owners. In 1921, the city renamed it Welfare Island to reflect its concentration of hospitals and charitable institutions. It wasn't until 1973 that it was officially renamed Roosevelt Island in honor of President Franklin Delano Roosevelt. This change accompanied a major urban redevelopment project intended to transform the island into a vibrant residential community. The name also pays tribute to the 32nd President's connection to New York and his legacy of public service, which is now physically memorialized at the southern tip of the island in the stunning Franklin D. Roosevelt Four Freedoms Park, designed by architect Louis Kahn and opened to the public in 2012.
