[1] Born in Dresden in 1909, the daughter of a railroad official, Eva Justin served as an assistant to Nazi psychologist Robert Ritter.

Her doctoral dissertation was titled "Lebensschicksale artfremd erzogener Zigeunerkinder und ihrer Nachkommen" ("Biographical destinies of Gypsy children and their offspring who were educated in a manner inappropriate for their species").

[11] She wrote in the foreword to a research paper that she hoped to provide the basis for further racial hygiene laws to stop the flow of "unworthy primitive elements" into the German population.

[12] Her position was that Romani people could not be assimilated because "they usually became asocial as a result of their primitive thinking, and that attempts to educate them should be stopped.

[16] In post-war West Germany, Justin worked as a psychologist for the Frankfurt police, even acting as a consultant to the legal system for compensation cases for Holocaust survivors.
