Siegfried Dehn

Siegfried Wilhelm (von) Dehn (24 or 25[1] February 1799 – 12 April 1858) was a German music theorist, editor, teacher and librarian.

While attached to the Swedish embassy in Berlin, Dehn developed an interest in musical research, studying with Bernhard Klein.

[2] In 1842, composer Giacomo Meyerbeer recommended Dehn to fill the post of custodian of the Prussian royal library.

Dehn threw himself into cataloging the collection, bringing it into order and adding to it copiously from libraries all over Prussia.

His students included Albert Becker, Ludwig Bussler, Peter Cornelius, Mikhail Glinka, Heinrich Hofmann, Gustav Nottebohm, and Anton Rubinstein.
