Austrian historian and theologian; born Oct. 18, 1867, at Priekopa, Hungary. In 1887 he began his theological studies at the Budapest Seminary, and at the same time studied in the department of philosophy of the university under Goldziher and Kármán. Büchler continued his studies at the Breslau Seminary, and in 1890 was graduated as Ph. D. at Leipsic University, his dissertation being "Zur Entstehung der Hebräischen Accente," which was afterward published in the "Sitzungsberichte der Wiener Akademie der Wissenschaften" of 1891.
Büchler returned to Budapest to finish his theological studies, and was graduated as rabbi in 1892. He then went to Oxford for one year, where he worked under the direction of his uncle, Dr. Adolf Neubauer, and published an essay, "The Reading of the Law and Prophets in a Triennial Cycle" (in "Jew. Quart. Rev." April, 1893). The same year he accepted a call as instructor at the Vienna Jewish Theological Seminary, where he still (1902) teaches Jewish history, Bible, and Talmud.
Büchler has published the following works: "Die Priester und der Cultus im Letzten Jahrzehnt des Tempelbestandes," Vienna, 1895, "Die Tobiaden und die Oniaden," ib. 1899; "Das Grosse Synedrion in Jerusalem und das Beth-Din in der Quaderkammer des Jerusalemischen Tempels," ib. 1902. He has also contributed some essays to the "Jewish Quarterly Review," the "Monatsschrift," the "Revue des Etudes Juives," and other periodicals, mainly on the last days of the Second Temple, which essays have attracted much attention on account of their originality.
