Benzion Netanyahu studied in the David Yellin teachers' seminary and the Hebrew University of Jerusalem. Although his father was a rabbi, Benzion was secular.[4] His younger brother, mathematician Elisha Netanyahu, became Dean of Sciences at the Technion. It was a common practice for Zionist immigrants at the time to adopt a Hebrew name.[5] Nathan Mileikowsky began signing some of the articles he wrote "Netanyahu," the Hebrew version of his first name, and his son adopted this as his family name.
