Konrad Weiss (1891 – 1976) was an Austrian radiologist.

Born and raised in Vienna, Austria, he attended medical school at the University of Vienna in 1910. Called to service during the first world war, he was decorated with the golden medal of valor by the Austro-Hungarian army.

He graduated in 1916, and whilst working at a military reserve hospital, he first came into contact with the emerging field of Radiology, which he would come to love. In 1920 he began working alongside contemporary Robert Kienböck at the Vienna Institute of Radiology, where he would stay for nearly 40 years, and develop groundbreaking recognitions in pathology and anatomy of bone and joint diseases.

Weiss is credited with early descriptions of Müller-Weiss syndrome, the dissecting aortic aneurysm, and gastric torsion. He was a founding member of the Austrian Radiological Society.

Medical Eponyms
Müller-Weiss syndrome (MWS) (1929)

Spontaneous osteonecrosis of the tarsal navicular in adults, is a rare cause of chronic medial midfoot pain.

Complex idiopathic foot condition with deformity of the tarsal navicular. Commonly presents in adulthood with chronic mid and hindfoot pain. Distinct from Köhler disease, the osteochondrosis of the tarsal navicular bone in children. 

Georg Schmidt first reported the condition in a patient with “pluriglandular insufficiency syndrome” in 1925. In 1927, German orthopedic surgeon, Walther Müller (1888–1949) reported a case of MWD and attributed it to mechanical collapse from compressive forces. One year later, he proposed a congenital theory as the cause of the condition

In 1929, Weiss presented 2 cases with similar findings. Based on radiographic signs of increased bone sclerosis and adjacent joint space narrowing, he attributed the condition to osteonecrosis.
