28 out of 29 people in this picture received a Nobel Prize.
So, who was the absolute disgrace/loser/#nonobel? ^_^
I was curious about that too, so I asked the allmighty google. I only remember that Planck was on that picture, and only recognize Einstein.
I found first the 9gag thread where cutlass probably has it from. The comments in there say it's only 17 of 29. I checked further, found https://rarehistoricalphotos.com/solvay-conference-probably-intelligent-picture-ever-taken-1927/ , which also says that.
I (like everyone else) do not know by heart who got the Nobels, but google says that from the first 4 only 1 got a Nobel, so it's not 28/29.
Embarrassingly I only know 7 of them. On the plus side, it's not my research field.
