Russian Connection

Tracing the roots — Kyiv (Ukraine)

Born in Kyiv in 1916 and brought to British Mandatory Palestine as a child, Katzir was a product of the Russian-Jewish emigration that built Israel's scientific and political elite. His career — from Kyiv to Rehovot to the President's residence in Jerusalem — is the arc of an entire generation of Russian-Jewish immigrants who built the State of Israel.

Famous biophysicist turned President.
