Prof. Yisrael Aumann, Nobel laureate and one of the most prominent mathematicians in Israel and around the world, is a pioneering scientist whose discoveries guide the global economy and social relations. He has been designated a “Yakir Yerushalayim” – Honorable of Jerusalem. Prof Aumann was born in Frankfurt, Germany in 1930; from the age of eight, he grew up in New York. He studied at academic institutions in New York and as a gifted mathematician, he went on to MIT University, to study game theory. Although a bright academic future lay ahead of him in New York, he immigrated to Israel during Operation Sinai and settled in Jerusalem, where he raised his five children with his wife Esther. Esther is the daughter of Dr. Falk Schlesinger, one of the pioneers of medicine in Israel and director of Shaare Zedek Medical Center. After his eldest son Shlomo lost his life in the Lebanon War, he founded the Shlomo Aumann Institute in his memory; the institute deals with Torah research and compares the formulations of the great Talmudic commentators. In 2005, following a long string of awards and honors previously received for his research, he won the Nobel Prize in economics for his important discoveries in the study of game theory.
