From the New York Times:
In the Cemetery of the Evergreens on the border of Brooklyn and Queens, there is a haunting stone monument to the garment workers who died in the Triangle shirtwaist factory fire of 1911 but were never identified. It contains the bas-relief figure of a kneeling woman, her head bowed, seemingly mourning not only the deaths, but also the fact that those buried below were so badly charred that relatives could not recognize them.
Almost a century after the fire, the five women and one man, all buried in coffins under the Evergreens monument, remained unknown to the public at large, though relatives and descendants knew that a loved one had never returned from the burning blouse factory.
Now those six have been identified, largely through the persistence of a researcher, Michael Hirsch, who became obsessed with learning all he could about the victims after he discovered that one of those killed, Lizzie Adler, a 24-year-old greenhorn from Romania, had lived on his block in the East Village.
