Kohn was born into a
German-speaking Jewish family in
Prague,
Bohemia, then part of the
Austro-Hungarian Empire. After graduating from a local German
Gymnasium (high school) in 1909, he studied philosophy, political science and law at the German part of
Charles-Ferdinand University in Prague. Shortly after graduation, in late 1914 Kohn was called into the infantry of the
Austro-Hungarian Army. Following training he was sent to the
Eastern Front in the
Carpathian Mountains, facing the
Imperial Russian Army. He was captured in 1915 and taken by the Russians to a prison camp in Central Asia (in present-day
Turkmenistan). During the
civil war following the Bolshevik revolution, the pro-western
Czechoslovak Legions came into Central Asia and he was set free. With them he traveled further east (called by Czechs the
"Siberian Anabasis"), until stopping at
Irkutsk. The political situation then allowed him to return to Europe, arriving in 1920. Kohn then lived in
Paris, where he married Jetty Wahl in 1921. The couple moved to
London, where Kohn worked for
Zionist organizations and wrote articles for newspapers. He moved to
Palestine in 1925. From there he would frequently visit the United States. His writings began to generate books, where he discussed current geopolitics and nationalism. In 1929, he wrote a resignation letter from
Keren HaYesod titled "Judaism is Not Zionism". Following the
Hebron massacre three months prior, he wrote a following letter: Eventually the couple immigrated to America in 1934. They had one son, Immanuel Kohn. ==Career==
