sentences:  After the war, Dennison returned to work on molecular structure, as well as working on the design of the new synchrotron at Michigan.With Theodore H. Berlin, he developed the theory of stable orbits in a synchrotron with straight sections, a feature that soon became standard in most large synchrotrons.The David M. Dennison Building on the campus of the University of Michigan was originally named in his honor, but was remodeled and renamed as the Weiser building (in 2017) due to a large cash donation from Ron Weiser.
