Answer to Question #1469 Submitted to "Ask the Experts"

Category: Historical Issues/Applications

The following question was answered by an expert in the appropriate field:

I have a .jpg file of a painting by M. Parrish of a group portraying the key nuclear physicists involved in the Manhattan Project at the University of Chicago. It is easy to identify Fermi, but I would like one of your experts to see how many of the other people can be identified. I am an emeritus HPS member. My daughter works at the University of Chicago art museum which is in possession of the painting. They are eager to identify the scientists.

I have identified the individuals in the painting as best as I can. The names are superimposed on the body of the individual in the attached image. The color used for the name indicates the level of certainty/uncertainty of the identification. A name indicated in blue is almost certain (for example, 90% plus) to be correct. A name indicated in yellow is quite probably correct (for example, 70 - 90%). A name indicated in orange is likely but suspect (for example, 50 - 70%). The detail on some of the individuals' faces toward the back is not sufficient for me to even hazard a guess. Of a pool of 50 or so potential candidates (the number of individuals who were present at the depicted event), only 19 are shown in the painting.
