The fire at the Triangle Waist Co. on March 25, 1911, which shocked the United States and prompted the introduction of nationwide workplace safety regulations, claimed the lives of 146 workers. Until now, six victims were unidentified.

Independent researcher Michael Hirsch discovered the identities of the final six victims through extensive genealogical research, using a wide array of resources, including those found on the Kheel Center's Triangle Factory Fire Web exhibit.

A documentary about the victims, Hirsch's work and the legacy of the fire are featured in the HBO documentary, "Triangle: Remembering the Fire," premiering March 21.

"Michael Hirsch's discovery honors the memory of the victims, who perished in a senseless tragedy," said Patrizia Sione, interim director of the Kheel Center.

An archive dedicated to the preservation and dissemination of information about the history of labor and management, the Kheel Center collects and preserves many original documents and secondary sources on the Triangle fire. The center is part of the Martin P. Catherwood Library at the ILR School.
