Harold Weitzner is an American applied mathematician and physicist whose primary research is plasma physics. He is Professor Emeritus of Mathematics at the Courant Institute of Mathematical Sciences and has served as Director of the Magneto-Fluid Dynamics Division at Courant since 1981, succeeding Harold Grad. He has published over 120 research articles on the topics of plasma physics, magnetohydrodynamics, fluid mechanics, fractional equations and kinetics, and chaos.
Professor Weitzner received his Ph.D. in 1958 from Harvard University on the topic of "Hyperon-Nucleon Interactions".
In 1981 he was elected a Fellow of the American Physical Society.
