Bob Rescorla, a member of Penn’s Psychology faculty from 1981 to 2009, passed away on March 24. He was widely regarded as the heir to Ivan Pavlov, and one of modern psychology’s preeminent experimental methodologists. Rescorla’s work on learning processes, most famously in the Rescorla-Wagner model, is still an important reference point after almost fifty years. To his colleagues and former students, he is remembered as one of our most inspirational classroom teachers, and a generous and wise advisor and leader. He is missed by all of us who were fortunate to know him. For more information, please visit https://almanac.upenn.edu//#robert-rescorla-psychology
