Leon Lederman, the US particle physicist who shared the 1988 Nobel Prize for Physics with Melvin Schwartz and Jack Steinberger, died on 3 October aged 96.
I happened to receive a letter type-written by Leon Lederman's secretary and signed by Lederman because I wished in 1979 to visit Fermilab, where he was the director at that time. I submitted his letter along with other overseas travel documents to the administrative department of the Radiation Center of Osaka Prefecture. So, I now have its Xerox copy only (see the photo).
