[The military radiologist Etienne Henrard (1870-1941) ... or the Belgian doctor Hirtz]. / Le radiologue militaire Etienne Henrard (1870-1941) ... ou le docteur Hirtz belge.

Etienne Henrard was undoubtedly the most important Belgian military radiologist. Besides his clinical radiological activities, he quickly became interested in stereoradiography and the removal of foreign bodies, which earned him international fame. During the First World War he continued his work and improved his techniques in the hospital "L'Océan" at De Panne, in collaboration with Antoine Depage. He was a Founding fellow member of the "Société belge de Radiologie" and of the "Journal belge de Radiologie", of which he was the Secretary (1909-1912), Vice-President (1913-1914), Président (1919-1920), Editor-in-Chief (1924-1940), and finally Treasurer (1932-1940). He was a founding fellow member, and later the President (1924-1938) and Honorary President of the "Union professionnelle des Médecins belges Radiologistes". He was the Honorary President of the Third Congress of Radiology in the French-speaking world. He was due to receive an international tribute, but an unfortunate date had been chosen: May 19, 1940.
