In 1810 he became a finance directorate and from 1813 he worked as chief finance officer at the ministerial section for taxes and domains in Munich.

Affair palm

In addition to Johann Georg Leuchs (1761–1836), Count Julius von Soden , August Ernst von Steigentesch a . a. According to recent research ( Andreas Maislinger ), Julius Conrad Yelin is today ascribed the authorship of the writing Germany in its deep humiliation , published in 1806 by the Nuremberg bookseller Johann Philipp Palm and directed against Napoleon . At that time, a man named Yelin was managing director of the Passau branch of Palmschen Buchhandlung. At least this could also be the former Protestant pastor Philipp Christian Gottlieb Yelin (1745–1814), who was in Passau around this time after his dismissal as pastor of Wintershausen near Würzburg. Johann Philipp Palm refused to divulge the name of the author and was shot on the direct order of Napoléon Bonaparte on August 26, 1806 in Braunau am Inn after a quick trial.
