Austrian jurist and statesman; born in Vienna July 2, 1828. Having studied law at the university of his native city, he in 1850 was appointed assistant librarian, and in 1852 privat-docent, at his alma mater. The following year he was called to Prague as assistant professor at the university, and in 1855 to Vienna in a similar capacity. In 1857 he was appointed professor of jurisprudence at the latter institution. In 1867 he was successively elected a member of the Austrian Landtag and of the Reichsrath; but on account of ill health he had to resign in the following year. Appointed in 1869 by the Emperor of Austria a life-member of the House of Lords, he soon became the whip of the Liberal Party. Two years later he became minister (without portfolio) in Prince Auersperg's cabinet, but resigned upon the prime minister's defeat in 1879. In 1881 he was appointed president of the Reichsgericht (Supreme Court of Administration). Unger is a convert to Christianity.
