Francis Halzen was traveling for a science festival in Bergamo, Italy, when he learned last week that he was the recipient of the 2026 Nobel Prize in physics. When the University of Wisconsin–Madison physics professor returned to campus on Monday, Oct. 12, his colleagues were ready to celebrate the achievement. Members of the Wisconsin IceCube Particle Astrophysics Center (WIPAC) and the UW–Madison Physical Sciences Lab joined Halzen at the WIPAC office for a work party, complete with a Nobel-themed cake. His Department of Physics colleagues will host a similar celebration on Tuesday.
Although Halzen was the sole recipient of the physics prize — the first since 1992 — he has acknowledged his many colleagues and collaborators who have helped make his vision for the NSF IceCube Neutrino Observatory in Antarctica a scientific success.
“Congratulations, Francis!” When Nobel Prize winner Francis Halzen returned to campus on Monday, he was greeted by congratulatory notes from his colleagues attached to his office door.
