The picture of the Kosel below was taken by my grandfather Sidney (Nesanel) Siegfried. While I can’t pinpoint the exact time the picture was taken, I do know that it was taken in the early afternoon on Aug 1st, 1932 כ״ח תמוז תרצ״ב. I leave it to the readers of this post to try and calculate the exact time the picture was taken based on the shadows.
