Morton Orentlicher
Engineer of New York and Berkeley
From the Bronx to Berkeley, deriving the statistical mechanics of dense fluid mixtures alongside J. M. Prausnitz, and crossing the biological divide into Columbia Neurology to unlock the human mind through thermodynamics.

Chapter 1: The Bronx Architecture
Morton Orentlicher emerges from the Bronx, driven by an innate curiosity for the elegant mathematical laws that define the natural order. In autumn 1966, he uncaps his fountain pen at Berkeley, laying out a fresh pad of lined paper, a brass slide rule, and thermodynamic tables to confront the unsolved frontier of dense fluid mixtures.
"Since the structure of simple fluids at high densities is largely determined by hard-core molecular repulsions, the properties of such fluids must be closely related to those of rigid-sphere systems."

"Thermodynamic Properties of Dense Fluid Mixtures" established the foundational perturbation method based on hard-sphere molecular repulsions. It is renowned for the historic institutional footnote:
