Martin Buber (1878–1965) was a Jewish philosopher, writer, and educator best known for his “philosophy of dialogue” – the idea that human life is shaped through genuine encounter and relationship.
Born in Vienna, Buber became an honorary professor of the history of religion at the University of Frankfurt in 1930. He left his position after Adolf Hi**er became chancellor in 1933 and emigrated to Palestine in 1938. In 1955, he was among the founders of the Leo Baeck Institute.
The LBI’s Martin Buber holdings include more than 1,000 letters and nearly as many pages of handwritten material, with a particular focus on the first three decades of the twentieth century, the years in which Buber developed many of his most influential ideas.
Among the collection’s most important materials are records of Buber’s close friendship and collaboration with philosopher Franz Rosenzweig (1886–1929). After meeting in 1914, the two worked together on literary and educational projects, including their influential German translation of the Hebrew Bible, Die Schrift, and their connection to the Freies Jüdisches Lehrhaus in Frankfurt.
The collection includes letters, cards, notes, and manuscripts that trace their conversations about philosophy, politics, teaching, family life, Buber’s journal Der Jude, and the practical work of translating the Bible. It also holds notebooks connected to the Buber-Rosenzweig translation – many dictated by Rosenzweig after illness left him paralyzed. The first volume appeared in 1925; Buber completed the translation in 1961.
Through these papers, the Leo Baeck Institute preserves not only Buber’s ideas, but the friendships, collaborations, and intellectual labor behind them.
