# Eri Jabotinsky

Eri Jabotinsky (Hebrew: עֵרִי זַ׳בּוֹטִינְסְקִי, also transliterated Ari, 26 December 1910 – 6 June 1969) was a Revisionist Zionist activist, Israeli politician and academic mathematician. He was the son of Ze'ev Jabotinsky, the founder of the opposition movement within Zionism at the time, and later served in the Knesset between 1949 and 1951, as a member of the opposition Herut party of Menachem Begin. Following his break with the party, he pursued his academic career.

## Biography

Jabotinsky was born in Odessa in the Russian Empire in 1910. In 1919 the family emigrated to British-controlled Palestine. Following the arrest of his father the following year, he moved to France, attending high school in Paris and later earning a degree in electrical engineering. Between 1933 and 1935 he worked as an engineer in an aircraft factory. In 1935 he returned to Palestine, and worked as an engineer at the Naharayim power station in the Jordan Valley.
A long-term member of Revisionism's Betar youth movement, he became one of its representative leaders in 1936, and joined its worldwide board two years later. With Betar and the party's military wing, Irgun, he helped coordinate illegal Jewish immigration into Palestine. He was arrested by the British authorities in November 1937 and imprisoned in Acre Prison until February 1938. He was later imprisoned again in 1940, and held for six months. Upon his release he moved to the United States, where his father soon died suddenly. There, together with Hillel Kook's 'Bergson Boys', Aryeh Ben-Eliezer, Shmuel Merlin and Yitzhak Ben-Ami among others, he founded the Emergency Committee to Save European Jewry. He briefly returned to Palestine, but was again arrested by the British and expelled for illegal activities in 1944.
Following Israel's independence he returned to the country in 1948, and was elected to the first Knesset the following year, as a member of the Herut party's list of candidates. On 20 February 1951 however, Jabotinsky and Hillel Kook left Herut, and sat as independents for the rest of the term, although the move was not recognised by the house committee. This followed on from disagreements over the party's direction and its new leadership by Menachem Begin.
After leaving the Knesset, he earned a PhD in mathematics in 1957 from the Hebrew University of Jerusalem. He also lectured on electricity theory at the Technion between 1955 and his death in 1969.
He was the father-in-law of Anatoly Rubin.
