'Classic Papers' in this issue of Acta Radiologica.

Abstract

In this issue of Acta Radiologica we present two articles written by two pioneers from the early years. The first article was written by the Norwegian surgeon Christian Magnus Falsen Sinding-Larsen (Fig. 1). SindingLarsen was born in 1866 in Oslo (at that time named Kristiania), and obtained his MD in 1891. From 1892 he was affiliated to the Surgical Departments A and B at Rigshospitalet. His main interest was skeletal tuberculosis in especially children, and he was from 1892 candidate and thereafter consultant and Chief surgeon at ‘‘Kysthospitalet’’ at Stavern, Norway, at that time being a hospital for children with scrofulosis. In later years it became a hospital specialized in orthopedic surgery, today a rehabilitation center. In 1907 he obtained his PhD degree with his publication ‘‘Beitrag zum Studium der Huftgelenks tuberculose’’. In the following years he had several study periods at hospitals in Germany, Austria, France, and Denmark. In 1911 he was appointed managing director at Rigshospitalet in Oslo/Kristiania. Sinding-Larsen had several radiological publications even if he originally was educated as a surgeon, with more than 70 publications concerning surgical topics, but also articles as ‘‘Roentgen treatment of surgical tuberculosis’’ (1925) and ‘‘Don’t forget to obtain an X-ray image of serious back trauma’’ (1927). He was a man with many interests in topics other than surgery and radiology, and he also authored publications as ‘‘Necessary equipment in Prisons in the treatment of diseased prisoners’’ to ‘‘A letter to a fanatical total abstainer’’. On 12 February 1930 he gave a presentation at a meeting of the Norwegian Medical Society. Immediately after his presentation he had a serious heart attack, and was brought to the hospital where he died of a cardiac infarction the same evening. It was said that ‘‘he died with his boots on’’. In this issue of the ‘‘Old Classics’’ we present his article from 1921 about ‘‘An Hitherto Unknown Affection of the Patella in Children’’ (1). The second article in this month’s issue was written by the famous Danish professor Poul Flemming Moller (Fig. 2). He was born in 1885 and died in 1974. He became a medical candidate in 1911. As many radiologists at that time, he started his career first in epidemiology, and later, i.e. in 1914, he studied surgery in Germany. From 1916 he became an assistant at the radiological department at Rigshospitalet in Copenhagen, and later on he was appointed as radiologist and chief of the radiological department of Fredriksbergs hospital in 1920–1930. In 1930 he was appointed Chief of Rigshospitalet’s radiological clinic and docent at the University of Copenhagen at the same time. From 1936 he became full Professor. As the author of the other article in this issue of the ‘‘Old classics’’, Flemming Moller was interested in tuberculosis, and in 1924 when he defended his thesis dealing with Calve-Legg Perthes disease, he could show
