Felix Landau (May 21, 1910 – April 20, 1983) was an SS Hauptscharführer, a member of an Einsatzkommando during World War II, based first in Lwów, Poland (today Lviv, Ukraine), and later in Drohobycz.

In return, he ordered the artist to paint a set of murals for his young son's bedroom, depicting scenes from the Brothers Grimm fairy tales.

Landau also was the SS officer assigned to watch over Maria Altmann, the subject of the 2015 film Woman in Gold.

The conditions of his release were stringent, requiring him to report to the authorities on a daily basis, not go outside after 8:00 PM, not use a telephone or any kind of transportation.

He began his diary in July 1941, interspersing sentimental letters to his fiancée with detailed records of his participation in actions related to the Holocaust.

In one such event in November 1942, Landau killed the personal dentist of a fellow officer, Karl Günther.

According to Schulz's friend Izydor Friedman, who witnessed the death, this happened at the corner of Czacki and Mickiewicz Streets.
