Elisha Netanyahu (Hebrew: אֱלִישָׁע נְתַנְיָהוּ; December 21, 1912 – April 3, 1986) was an Israeli mathematician specializing in complex analysis. Over the course of his work at the Technion he was the Dean of the Faculty of Sciences and established the separate Department of Mathematics. Historian Benzion Netanyahu was his brother and Benjamin Netanyahu, current Prime Minister of Israel is his nephew.
Netanyahu was born in Warsaw, Poland, to the writer and Zionist activist Nathan Mileikowsky. He was the third of nine children. In 1920 the family made aliyah to the Land of Israel. The family eventually settled in Jerusalem and adopted Hebrew name Netanyahu.
Netanyahu went to the Reali School in Haifa, from which he graduated in 1930. He later returned to Reali in 1935 to teach mathematics there. He studied at the Hebrew University of Jerusalem, from which he received his BS, MA and PhD (1942). His advisors were Michael Fekete and Binyamin Amira. After the graduation he joined the British Army as a volunteer, serving in Egypt and then in Italy as an officer in a unit of the Royal Engineering Corps. He specialized in preparation of maps, which he continued to do during Israel's War of Independence in 1948.
After he was demobilized in 1946, he became a lecturer at the Technion. He rose to a professor in 1958, and later became the head of the Mathematics Section, then as Dean of the Faculty of Sciences. His administrative efforts also played an important role towards establishment of the Ben-Gurion University of the Negev.
He had long term visits at Stanford University (1953–54), the Courant Institute (1961), the University of New Mexico (1969), the University of Maryland, College Park (1973), and ETH Zürich (1979). In 1980, Netanyahu retired from the Technion and moved to Jerusalem, where he died of cancer in 1986.
In 1949 Netanyahu married Shoshana Shenburg, his former student at the Reali, who later became the second female justice at the Israel Supreme Court. They had two children: Nathan (b. 1951), a professor of computer science at Bar-Ilan University, and Dan (b. 1954), an information systems auditor.
