Frances Perkins (above) was having tea with friends at Margaret Morgan Norrie’s home on Washington Square on Saturday afternoon, March 25, 1911 . . . The clang of fire trucks interrupted their conversation and they hurried across the Square to discover the cause. They reached the Asch Building, site of the Triangle Shirtwaist Company, in time to see young women, many on fire, jumping to their deaths. 146 human beings perished.
