  Z. Schuss (1937-2018) was an applied mathematician, with several
contributions in asymptotic, stochastic processes, PDEs, modeling and signal
processing. He is well known for his original approach to the activation escape
problem, based on WKB and boundary layer analysis, summarized in six books
published by Springer. The text summarizes his intellectual approach in
science, views and personal path across the XX century, WWII and his personal
contribution to academia.
