On March 23, 1954, Walter Zinn held a farewell lunch at his laboratory for Alfonso Tammaro, who had been Zinn’s local Atomic Energy Commission manager in Chicago. My impression is that there had many tussles been Zinn, the scientist, and Tammaro, an engineer, but that there was also plenty of respect and amity. I found this letter to Alfonso:
What was this “paper weight”? Is this a private joke between the two or did Zinn really make a memento of, say, his famous EBR-I four-light-bulb moment? If the latter, such a memento would be indeed wonderful. Sadly, I think we’ll never know: I’ve seen nothing more about this.
