1923 deaths

Wilhelm Conrad Röntgen (; German pronunciation: [ˈvɪlhɛlm ˈʁœntɡən] ; 27 March 1845 – 10 February 1923) was a German mechanical engineer and physicist, who, on 8 November 1895, produced and detected electromagnetic radiation in a wavelength range known as X-rays or Röntgen rays, an achievement that earned him the inaugural Nobel Prize in Physics in 1901. In honour of Röntgen's accomplishments, in 2004 the International Union of Pure and Applied Chemistry (IUPAC) named element 111, roentgenium, a radioactive element with multiple unstable isotopes, after him. The unit of measurement roentgen was also named after him.

Auguste-Maurice Barrès (French: [baʁɛs]; 19 August 1862 – 4 December 1923) was a French novelist, journalist, philosopher, and politician. Spending some time in Italy, he became a figure in French literature with the release of his work The Cult of the Self in 1888. In politics, he was first elected to the Chamber of Deputies in 1889 as a Boulangist and would play a prominent political role for the rest of his life.

Marie-Thérèse Glaesener-Hartmann (1858–1923) was a Luxembourg painter. She is remembered for painting the portraits of prominent figures of the times, including Prime Minister Paul Eyschen (1841–1915) and the mayor of Luxembourg City Alphonse Munchen (1850–1917). She exhibited at the Cercle artistique from 1894 to 1912.

Paul Marie Oudin (1851–1923) was a French physician and medical researcher. He was born, and later died, in Épinal. He conducted research in the Victorian era medical field of high frequency electrotherapy, the application of radio frequency electric currents to the body, and collaborated with the founder of the field, pioneering physiologist and biophysicist Dr. Jacques Arsene d'Arsonval. In 1893 he modified d'Arsonval's electrotherapy equipment by the addition of a wire coil resonator to produce higher potentials, inventing the Oudin coil. This device, very similar to a Tesla coil, could produce very high voltages from several hundred thousand to a million volts. In use, the brush discharges from a pointed electrode attached to the high voltage terminal of the coil would be played over various parts of the body to treat a variety of medical conditions. The Oudin coil was used in electrotherapy and diathermy through the 1920s.

Gustaf Adolf Britsch (11 August 1879 – 27 October 1923) was an early 20th-century German art theorist and the founder of Gustaf Britsch Institute in Starnberg, Germany.

Robert Ernst Eduard Wiedersheim (21 April 1848 – 12 July 1923) was a German anatomist who is famous for publishing a list of 86 "vestigial organs" in his book The Structure of Man: An Index to His Past History.

María Arias Bernal, also known as María Pistolas (1884–1923), was a schoolteacher who was an agitator in the Mexican Revolution under Francisco I. Madero, president of Mexico 1911–1913, until his assassination in a counter-revolutionary coup by Victoriano Huerta. Arias is noted for her defense of Madero's tomb in Mexico City, despite the threat of the Huerta regime.

Otto Böckel (2 July 1859, Free City of Frankfurt – 17 September 1923, Michendorf) was a German populist politician who became one of the first to successfully exploit antisemitism as a political issue in the country.

Jkvr. Jacoba Berendina van Heemskerck van Beest (1876–1923) was a Dutch painter, stained glass designer and graphic artist who worked in several modern genres. She specialized in abstract landscapes and still-lifes.

Theodor Rumpel (25 March 1862, Gütersloh – 11 August 1923, Hamburg) was a German surgeon remembered for describing the Rumpel-Leede sign.
He received his doctorate in 1887 in Marburg and worked at the Hamburg-Eppendorf Hospital. He oversaw the building of the Barmbecker Krankenhaus in Hamburg, of which he became director in 1913. Among his better known assistants at Hamburg was bacteriologist Georg Jochmann.With internist Alfred Kast, he was co-author of a patho-anatomical atlas titled: Pathologisch-anatomische Tafeln nach frischen Präparaten mit erläuterndem anatomisch-klinischem Text.
