Joseph Hirsch (Tzvi) Carlebach (January 30, 1883, Lübeck, German Empire – March 26, 1942, Biķerniecki forest, near Riga, Latvia) was an Orthodox rabbi and Jewish-German scholar and natural scientist (Naturwissenschaftler).
Carlebach was the eighth child of Esther Adler (1853–1920), the daughter of the former rabbi of Lübeck, Rabbi Alexander Sussmann Adler (1816–1869), and Lübeck's then Rabbi Salomon Carlebach (1845–1919). In 1919 Joseph Carlebach and his former pupil Charlotte Preuss (1900–1942) married. They had nine children.
Joseph Carlebach became rabbi, like many of his brothers, to wit David Carlebach, Emanuel Carlebach (rabbi in Memel and Cologne), Hartwig Naftali Carlebach (rabbi in Berlin, Baden near Vienna and New York), and Ephraim Carlebach (rabbi in Leipzig). Joseph Carlebach completed extensive studies in natural sciences. From 1901 on he studied at Friedrich-Wilhelms-Universität in Berlin natural sciences, mathematics, astronomy, philosophy and history of art. The quantum physicist Max Planck and the philosopher Wilhelm Dilthey (hermeneutics) were among his teachers. In 1908 he graduated as high-school teacher (Oberlehrer-Examen) of natural sciences (at summa cum laude). In the same time Carlebach attended the orthodox Rabbinical Seminary in Berlin. In 1905 to 1907 Carlebach interrupted his studies in Germany and taught at the Lämel-School in Jerusalem. There Carlebach learned to know a number of excellent rabbis.
