==Louisiana State University==

In 1982 I joined the faculty in the Department of Physics &amp; Astronomy at Louisiana State University (LSU). I learned that, on a number of different occasions throughout the decade of the 70s, <font color="orange">Eugene Wigner</font> would leave Princeton (in the fall?) and spend a few months at LSU interacting primarily with physicists in the condensed-matter and atomic theory programs.  From what I have been able to ascertain from Wigner's published ''[https://books.google.com/books?id=6Hj1BwAAQBAJ&pg=PA303&lpg=PA303&dq=roger+richardson+and+eugene+wigner&source=bl&ots=KXnb0OfiWZ&sig=ACfU3U1rBwCN1IU9e9lV_73pcTGzp3q07w&hl=en&sa=X&ved=2ahUKEwi11MjC563iAhWCvp4KHX6SC5oQ6AEwCHoECAgQAQ#v=onepage&q=roger%20richardson%20and%20eugene%20wigner&f=false Recollections]'', he was initially invited to LSU by the dean of LSU's Engineering College, Roger Richardson, who, like Wigner, had been personally involved in the Manhattan project during World War II.  It seems clear as well, however, that part of the draw was an opportunity for Wigner to extend his research interactions with [https://www.lsu.edu/physics/alumni/callaway.php Joseph Callaway] &#8212; see, also, [http://theor.jinr.ru/~kuzemsky/callawbio.html here] &#8212; who completed his doctoral dissertation research in 1956 under Wigner's direction.

During the early 80s, Wigner made one last extended visit to LSU; it was either during the 1982-83 or 1983-84 academic year.  I happened to be scheduled to give a routine departmental seminar that semester and, given the stories that I had heard about Wigner's probing questions, I was a bit nervous when I found out that he would likely be in the audience.  The topic of my presentation was galaxy dynamics and, sure enough, relatively early in my presentation, Wigner asked a question.  He asked me to clarify what I had just said about the aspect ratios of disk galaxies and the overall linear dimensions involved.  After I answered this question, he replied in his heavy Hungarian accent, "Verrrry interesting.  I did not know that."  He told me afterward that he had enjoyed the talk.  I warmly remember this brief interaction with Professor Wigner.
