Last week saw the 104th anniversary of the Triangle Shirtwaist Fire. A commemoration was held at the site of the disaster, at the northwest corner of Washington Place and Greene St., which is now an N.Y.U. building, on Wed., March 25. In one of the deadliest fires in U.S. history, 146 garment workers perished, including 123 women, mostly Jewish and Italian immigrants, ages 16 to 23. Last Wednesday, labor members, school kids, workers and City Council Speaker Melissa Mark-Viverito were among those marking the tragic anniversary. They spoke about workers’ rights, the right to organize, income equality, safe workplaces, immigration and justice.
