William Guglielmo Niederland was born in Schippenbeil, East Prussia, the son of an orthodox rabbi, and in early life was exposed to both the classic Talmudic education and to the secular learning of the Realgymnasium of Würzburg, Bavaria.
After completing his medical studies at the University of Würzburg, Niederland went on to an internship and residency in medicine.
For years he served as an officer of the Department of Health for the industrial region of the Ruhr.
He investigated and documented the particular characteristics of their reactions, coining the term "survivor syndrome" in 1961.
