That was the unhelpful label on the back of this photograph I ran across accidentally a few weeks ago. I still don’t know what group this is or either when or where the image was taken, but I can’t help noticing Albert Einstein in the middle of the front row.
Oh, and that’s future Rice president William Houston two over to the left. So if pressed, I’d say it’s a bunch of physicists.
Bonus: Houston always kept a lab while he was president. He could get to it by way of the top of the cloister between Lovett Hall and the Physics Building.
