Hebraist and teacher of deaf-mutes; born in Nikolsburg, Moravia, March 20, 1813; died in Vienna May 1, 1899. Deutsch is remembered as a close student of rabbinical literature, and was an energetic collector of Hebrew books. He took great interest in the instruction of deafmutes; and when the "Allgemeines Oesterreichisch-IsraelitischesTaubstummen-Institut" was founded at Nikolsburg in 1844, he entered it as teacher. In 1852 this institution was moved to Vienna, and Deutsch became director, retiring in 1888. In 1859 he was decorated with the "Goldene Verdienstkranz," and in 1869 received the title "Kaiserlicher Rath." Pupils of Deutsch have been called to become teachers in the asylums of New York, London, and Budapest.
He was author of the following works: "Religionslehre für Israel. Taubstumme," Vienna, 1863; "Biblische Geschichte für Israel. Taubstumme," ib. 1863; "Wörtersammlung zur Gedächtnissübung für den Ersten Anschauungsunterricht Taubstummer Kinder," ib. 1881; "Wörter- und Aufgabensammlung für den Ersten Unterricht Taubstummer Kinder," ib. 1881; "Vorlege-Blätter zur Einleitung der Unentbehrlichsten Grammatischen Formen," Teplitz, 1877.
