David Bruce Cline (December 7, 1933 – June 27, 2015) was an American particle physicist known for his contributions to the discovery of the Higgs boson and the W and Z intermediate bosons. After receiving his Ph.D. from the University of Wisconsin-Madison, he went on to join the University's physics faculty and founded the “Pheno Group”. Shorthand for phenomenology, the group consisted of particle physicists designing and running experiments alongside developing theoretical models that went beyond the current standard model of particle physics. He later moved to UCLA where he became a Distinguished Professor of Physics & Astronomy for his contributions to the growth of the UCLA Physics & Astronomy Department.
