He was an elderly Russian, Lubavitcher chassid of the old school. Real, warm and as sincere an eved Hashem as I’ve ever met. He collected money for Kiryat Malachi in many Jewish communities, with tremendous mesirus nefesh.
Yup, he used to come to our cheder and camp and talk about the mesiras nefesh for yiddishkeit in Russia. He used to to cry too, I remember him from years ago and it left a major impression on the kids. A real chossid of old. יהא זכרו ברוך
Eta. I didn't remember him from his name, but from seeing his face now in the news I right away recognized that's him, so attaching it here maybe others knew him as well.
