Plaat, Lotte (Mme. von Strahl) (1895– )
Dutch psychometrist whom, for some time, the German police
regularly employed to trace criminals. She was born December
30, 1895. Plaat was under the observation of Drs. Paul
Sünner, Gustave Pagenstechner, Harms, Ludwig Jahn, Kasnacich,
and other scientists, who recorded significant results with
her. In 1930, important experiments in psychometry took
place at the National Laboratory of Psychical Research in
London at the conclusion of which Plaat left for the United
States where further experimental work was performed.
