Rashevsky, Nicolas (b. 1899, Chernikov, Russia, d. 1972, Holland, MI). Trained in Russia as a mathematical physicist Rashevsky immigrated to the United States in 1924. At the University of Pittsburgh, he conceived the idea of building a mathematical biophysics on the model of mathematical physics. Later moving to the University of Chicago, he developed a doctoral program in mathematical biology and created the Bulletin of Mathematical Biophysics. As part of his application of mathematical tools and concepts to areas as diverse as cellular and organismal form, nerve conduction and excitation, sociology, history, and driving an automobile, Rashevsky developed mathematized neural network theories of Pavlovian conditioning.
