It is with great sadness that we learned of the death of Zbigniew Galperyn, a participant in the Warsaw Uprising and president of the Warsaw Insurgents' Union. Mr. Galperyn was the subject of an interview conducted by the Warsaw Ghetto Museum as part of the project "The Home Army and the Tragedy of Polish Jews." His contribution was invaluable. We are deeply grateful for the kindness shown to our employees. We extend our condolences to his family and loved ones.
