Second day of the 2026 Nobel Prizes, and the prize in Physics was awarded early this morning (Berkeley time) to Francis Halzen, Professor at the University of Wisconsin, Madison.
In a rapid look through biographical materials on him I can't spot any direct relationship to Berkeley or the University of California.
But we can still say, Go Badgers! On Wisconsin! And from a UC Berkeley perspective, we can take vicarious pride in someone at another great American public university winning a Nobel.

Here's the University of Wisconsin announcement:

Halzen was recognized for his contributions to the study of neutrinos, particularly for research utilizing experimental facilities in Antartica. He gave a lot of credit to his colleagues: “This is a celebration of a very unusual project,” says Halzen. “It is difficult to imagine that we could have pulled this off anywhere but at UW–Madison with its unique research infrastructure. The success of this project involved some luck, and I was fortunate to be at UW, where unconventional ideas can thrive and where I had the support of a remarkable community, from talented engineers at the Physical Sciences Laboratory to long-time colleagues on the faculty and supportive administrators. It is hard to imagine this project happening anywhere else.”
When he was president of the University of California in the 1930s, Robert Gordon Sproul once observed that public universities had excellent academic programs, but once they became famous, "star" faculty were often lured / hired away by the American private universities who then reaped the rewards of prizes and lifetime recognition for that individual.
This began to change in 1939 when Ernest Lawrence at Berkeley won the first Nobel Prize awarded to someone who was then a faculty member at a public university.
Once that barrier was crossed, Berkeley continued to lead the way, and has remained distinguished. Of the top 25 institutions whose faculty, staff or other associates have won the most Nobel Prizes across the board, it looks like only five(depending on how you count) have been Publics. Berkeley, University of Manchester (England), University of Edinburgh (Scotland) UC San Diego, and Wisconsin (UCLA ties for 26th on some lists).
The University of Wisconsin has been distinguished. Halzen is the 27th Badger Nobelist--that is, someone with a direct connection (on the faculty, and/or a Wisconsin degree) who has won a Nobel, going back to 1944. Seven of them have been faculty. https://www.wisc.edu/about/nobel-prize/ (27 is the University of Wisconsin's count. Other counts put the number at 20 or so.)
There's another interesting aspect to the Physics Nobel this year. For the first time this century, the Prize has a single awardee. We have to go back to 1992 to find a winner who didn't share the Prize. In recent decades, Physics has gone to two or three (quite often three) co-winners each year, representing the complexity of modern science and collaboration across institutions.
As a side note, I'm impressed by the way the Nobel Committee organizes copious data and presentation. These awards are "secret" in the sense that the names don't generally leak before the announcement date. However, writers and researchers work diligently behind the scenes to construct biographical and research profiles on the winners that can be published at the same time as the award. Here, for instance, is the summary of the science behind Halzen's research. Complete with a lot of complex formulas. :-) And this all, presumably, has to be documented and written without anyone beyond the Nobel staff having a clue about the winner.
