HG"R Dov Yehuda Schochet zt"l,
in a a still from today's Siyum HaShas at Met-Life Stadium.
It is at 3:47:35 in the video at https://thesiyum.org/
My grandfather is the second from left, the person sitting, with the bow tie.
I am not sure where the AIA got the picture, this is the original.
Yasher koach to my cousin Harav Chaim Schochet shlita,
for spotting the picture.
I do not know who the others in the picture are, but the odds are overwhelming that they were killed in the Holocaust.
This is the entire clip l'zecher ha'Kedoshim, הי"ד זי"ע.
