Often overshadowed by the 1911 Triangle Shirtwaist Fire and the sinking of the Titanic in 1912, the General Slocum steamboat disaster on June 15, 1904, was nonetheless the deadliest New York City disaster prior to September 11, 2001. The official number of deceased was 1021 people: mostly women and children.
The legacy of this disaster not only includes the tremendous loss of life but the reshaping of an entire New York City neighborhood, Kleindeutschland. Already losing community members to Yorkville and the outer boroughs by the turn of the 20th century, the Slocum disaster accelerated the exodus of Germans from Little Germany and ushered in the more diverse immigrant communities that settled on the Lower East Side.
