Friedrich Wilhelm Seiffer

Friedrich Wilhelm Seiffer (18 April 1872 – 30 November 1917) was a German neurologist and psychiatrist born in Stuttgart.

In 1895 he received his medical doctorate from the University of Strasbourg, and subsequently worked at a private mental health institution in Pankow-Berlin.

In 1896 he was an assistant to Eduard Hitzig (1838–1907) at the psychiatric hospital in Halle.

In 1899 he began work at the psychiatric clinic of the Berlin-Charité, where he worked under Friedrich Jolly (1844–1904) and Theodor Ziehen (1862–1950).
