In 1931 Dr. Hellersberg earned her Ph.D. from the University of Heidelberg, Germany. After working in child guidance and adult education in Berlin, she arrived in the US sometime between 1935 and 1937. While at Wagner (1942-43) she taught courses in psychology and sociology. Hellersberg later co-developed the Horn-Hellersberg test, a projective personality test, which she described in her 1950 book The individual's relation to reality in our culture; an experimental approach by means of the Horn-Hellersberg test.
Hellersberg's personality test was described in the article below which was published in the American Journal of Orthopsychiatry in 1945.
