[A dermatologist and a rheumatologist define a syndrome. George Thibierge (1856-1926), Raymond J. Weissenbach (1885-1963)].

For decades, G. Thibierge and R.J. Weissenbach worked at the Hôpital St. Louis in Paris, one of the first and largest dermatological centers.In 1911 they described the occurrence of subcutaneous calcification in scleroderma patients, emphasizing that this was not a coincidental finding, but rather a causal link. Since then this syndrome has been given their names worldwide.Thibierge gave his attention solely to dermatology and venereology. Weissenbach initially concentrated on the overlapping areas between dermatology and rheumatology, such as gonococcal arthritis, joint disease in Lues and psoriatic arthritis. He later dealt with all areas of rheumatology, set up a large rheuma clinic at the hospital, wrote a series of authoritative books and a considerable number of individual papers. Thus he became a rheumatologist even before the specialty rheumatology existed.
