“An electron trapped in a magnetic field” is the description Jens Zorn (right), professor of physics, uses to describe a new outdoor sculpture that was unveiled Feb. 5. The sculpture marks the 50th anniversary of measurements on the electron’s intrinsic magnetism by H. Richard Crane (center), 96, professor emeritus, and his students at U-M. Crane’s pioneering work and its modern extensions are bedrocks of quantum electrodynamics. The sculpture was designed by Zorn and crafted by members of the Physics Department’s instrument shop—Dave Carter, Ted Webster and Jim Tice—along with tradesmen from Plant Operations—Josh Blackmon, Scott Smith, Steven Correll, Dan Waters and Rockey Bennett. Joining Crane at the ceremony were his daughter, Carol Kitchens (left), and granddaughter, Beth Crane. (Photo by Martin Vloet, U-M Photo Services)
