Lefferts General Hospital was "a 160-bed private hospital" housed in a "four-story brick building" that opened 1958 at 460 Lefferts Avenue. That location was previously Crown Heights Hospital. The hospital, which closed in 1978, was on a list of 11 hospitals that the State Health Department attempted to close in 1976, allegedly "to fill up the municipals." In 1979 the building was converted into a dormitory to house 400 Iranian boys, age 10 to 22,who came to the United States "after the fall of the Shah."
