Arno Nadel (October 5, 1878 – March 1943) was a Lithuanian musicologist, composer, playwright, poet, and painter.

Nadel was born in Vilnius, Lithuania, at the time of his birth, part of the Russian Empire, to an Orthodox Jewish family.

[1] In 1895, when he was 17 years old,[2] he moved to Berlin and enrolled in the Hochschule für die Wissenschaft des Judentums.

In 1922, at the request of Jewish leadership, Nadel worked for years on an anthology of synagogue music, Kompendium Hallelujah!

[4][5][6] Before he was deported, Nadel was able to leave his large collection of old Jewish liturgical materials with a non-Jewish neighbor,[7] some of which survived and were purchased by his friend Eric Mandell.
