Schreus was described as a typical son of the mountainous landscape he grew up in. He was technically gifted and only reluctantly commenced the study of medicine. He excelled in contradictions, advocated the freedom of thought and supported his collaborators. Among his chief research areas were tropical dermatology and dermatopharmacology. He made fundamental contributions to dosimetry of X rays as well as the development of X ray machines.
