Roy Glauber 1925–2018

I saw (initially from Peter Woit's blog) that Roy Glauber died a few days ago.  Glauber's name is known to nuclear physicists for his approximate treatment of scattering theory which can be applied to nuclear collisions at high energies.  It was an ingredient in some of the seminal work from the nuclear theory group in Surrey when we became the go-to people for the reaction theory needed to understand the reaction of halo nuclei, and the extraction of their sizes. I say "we" – this was slightly before my time at the group.  Here is a paper by Jim Al-Khalili and Jeff Tostevin from 1996 on the subject of nuclear sizes, making use of Glauber theory. 

Nuclear Physics was a relatively small part of Glauber's work.  His biggest thing, at least the thing that got him the Nobel Prize, was his foundational work on quantum optics.  The picture attached to this post is Glauber at the Nobel Prize Ceremony in 2005, courtesy of Wikipedia.
