Early years 
Baeck was born in Lissa (Leszno) (then in the German Province of Posen, now in Poland), the son of Rabbi Samuel Baeck, and began his education at the Jewish Theological Seminary of Breslau in 1894. He also studied philosophy in Berlin with Wilhelm Dilthey, served as a rabbi in Oppeln, Düsseldorf, and Berlin, and taught at the Hochschule für die Wissenschaft des Judentums (Higher Institute for Jewish Studies). In 1905 Baeck published The Essence of Judaism, in response to Adolf von Harnack's The Essence of Christianity. This book, which interpreted and valorized Judaism through a prism of Neo-Kantianism tempered with religious existentialism, made him a famous proponent for the Jewish people and their faith. During World War I, Baeck was a chaplain in the German Imperial Army.
Nazi persecution and deportation 
In 1933, after the Nazis seized power, Baeck worked to defend the Jewish community as president of the Reichsvertretung der Deutschen Juden, an umbrella organization that united German Jewry from 1933 to 1938. After the Reichsvertretung was disbanded during the November Pogrom, the Nazis reassembled the council's members under the government controlled Reichsvereinigung. Leo Baeck headed this organization as its president until his deportation. On 27 January 1943, he was deported to the Theresienstadt concentration camp.
Leo Baeck became the "honorary head" of the Council of Elders (Judenrat) in Theresienstadt. As such, he was protected from transports and with his protection list, could also save his relatives from transports, among others his grand-niece Ruth (b. 1925). Moreover, Baeck became "prominent", which meant that he had better accommodation, better food and could receive mail more often. He gave lectures, was active in the interfaith dialogue between the Jews and Christians of Jewish origin, worked in the youth care sector, which he directed from November 1944 on, and was friendly with many of the functionaries. After liberation, he headed the Council of Elders; the last Elder of the Jews was the Czech communist Jiří Vogel. Baeck's lectures were credited with helping prisoners survive their confinement. Heinrich F. Liebrecht said Baeck's lectures helped him to discover wellsprings of strength and the conviction that his life had a purpose. "From here came the impulse to really endure, and the belief that we were able to do so."
Up until his deportation, numerous American institutions offered to help him escape the war and immigrate to the United States. Leo Baeck refused to abandon his community and declined the offers. Nevertheless, he managed to survive the Holocaust, though three of his sisters perished in the ghetto.
Post-war life and work 
After the war, Baeck relocated to London, where he accepted the Presidency of the North Western Reform Synagogue in Temple Fortune. He taught at Hebrew Union College in America, and eventually became Chairman of the World Union for Progressive Judaism. It was during this time he published his second major work, This People Israel, which he partially penned during his imprisonment by the Nazis.
In 1955, the Leo Baeck Institute for the study of the history and culture of German-speaking Jewry was established, and Baeck was the first international president of this institute. The asteroid 100047 Leobaeck is named in his honour, as is Leo Baeck College, the Reform/Progressive rabbinical college in London.
He died on 2 November 1956, in London, England.
