Not many Jews today know of the 19th-century Jewish leader who wrote a booklet that inspired young Jews to move to the Land of Israel. The man at first believed passionately in assimilation as an answer for Jews but later, due to what he saw as rising antisemitism, advocated a new idea that eventually became known as Zionism. He met with notables all over Europe to advance his plans. The booklet made an impact and led to his chairing a movement that convened a groundbreaking convention of Jews who came from all over Europe to speak about practical ways to spark a mass Return to Zion.
If you are thinking the man was Theodor Herzl, the book was The Jewish State (1896), the convention was the First Zionist Congress, and the movement was the World Zionist Organization, you are wrong.
This Jewish leader died five years before Herzl wrote The Jewish State, his name was Leon Pinsker, and this year is the bicentennial of his birth. Pinsker’s booklet was titled Auto-Emancipation: A Warning of a Russian Jews to His Brothers, and was published in 1882. The 1881 pogroms that followed the assassination of Czar Alexander II had caused Pinkser, a physician, to rethink his dedication to the idea that assimilation was the best hope for the Jews of Russia. He was recruited to the Hibat Zion (“Fondness For Zion”) movement and chaired its 1884 conference in Katowice, Poland, a result of which was that the various parts of the movement united as Hovevei Zion (“Lovers Of Zion”).
