Ira M. Cohen

(Deceased Dec 2007) Favorite Memory of attending “Brooklyn Poly”: Meeting wife on school picnic, June 1958. Career Highlights: Dr. Cohen was a world-renowned scholar in the areas of continuum plasmas, electrostatic probe theories and plasma diagnostics, dynamics and heat transfer of lightly ionized gases, low current arc plasmas, laminar shear layer theory, and matched asymptotic in fluid mechanics. Most of his contributions appear in the Physics of Fluids journal of the American Physical Society. His seminal paper, Asymptotic theory of spherical electrostatic probes in a slightly ionized, collision dominated gas (Phys. Fluids:1492-1499, 1963) is to-date the most highly cited paper in the theory of electrostatic probes and plasma diagnostics. During his doctoral work and for a few years beyond that, Dr. Cohen collaborated with the world-renowned mathematician/physicist, the late Dr. Martin Kruskal (recipient of National Medal of Science,1993) on the development of a m
