1923 deaths

Emil_G._Hirsch

Emil Gustav Hirsch (May 22, 1851 – January 7, 1923) was a Luxembourgish-born Jewish American biblical scholar, Reform rabbi, contributing editor to numerous articles of The Jewish Encyclopedia (1906), and founding member of the NAACP.

Johannes_Orth

Johannes Orth (14 January 1847 – 13 January 1923 in Berlin) was a German pathologist born in Wallmerod.
He studied medicine at the universities of Heidelberg, Würzburg and Bonn, receiving his habilitation in 1872 while an assistant to Eduard von Rindfleisch at Bonn. Afterwards, he served as an assistant under Rudolf Virchow (1821-1902) in Berlin. In 1878 he became a professor at the University of Göttingen, and in 1902, following the death of Virchow, he returned to Berlin as director of the clinic of pathology.
Orth specialized in the pathological study of infectious diseases, particularly tuberculosis and endocarditis.
In 1875, he documented an account involving an autopsy of a jaundiced infant with intense yellow staining of the basal ganglia, hippocampus, the third ventricle, as well as parts of the cerebellum. However, it wouldn't be until the early 20th century that this condition would be further comprehended. In 1903, pathologist Christian Georg Schmorl (1861-1932) presented the results of 120 autopsies of jaundiced infants, with six of the cases having the staining phenomena described by Orth. Schmorl coined the term "kernicterus" (jaundice of the basal ganglia) for the yellow staining phenomenon.

Maurice_Leblanc_(engineer)

Maurice Leblanc (1857 – 1923) was a French engineer and industrialist.
Born in Paris, Leblanc worked primarily in improving induction motors and alternators, where he invented the damper winding. He also invented an improved vacuum pump and worked in the area of refrigeration.
The December 1, 1880 French publication "La Lumière électrique", published an article by Leblanc entitled "Etude sur la transmission électrique des impressions lumineuses". In this article Leblanc outlined five functions required for a television system.

a transducer to convert light into electricity
a scanner to break up a picture into its constituent parts
a method of synchronising the receiver and the transmitter
a means of converting electrical signals back into light
a screen for viewing the imageLeblanc was awarded the Prix Poncelet for 1913 by the French Academy of Sciences.

Carl_von_Hess

Carl von Hess (7 March 1863, in Mainz – 28 June 1923, in Possenhofen) was a German ophthalmologist known for his work in ocular physiology.
He studied medicine at the universities of Heidelberg, Bonn and Strasbourg, then traveled to Prague, where he worked with ophthalmologist Hubert Sattler and physiologist Ewald Hering. In 1891 he obtained his habilitation from the University of Leipzig, and later on, he held professorships at the universities of Marburg (from 1896), Würzburg (from 1900) and Munich (from 1912).He made significant contributions in his studies of refraction and accommodation of the eye. He also conducted research on color vision in the various retinal zones, on the various forms of color blindness, of simultaneous contrast, on afterimages of moving objects and of light-dark adaptation. In addition, he performed comparative physiological studies on light sense and color vision involving animals, in invertebrates as well as vertebrates. Along with Paul Römer, he made the discovery that trachoma is transmissible to monkeys.His name is associated with the "Hess afterimage", defined as a positive afterimage that occurs third in the series of afterimages that are the result of exposure to a brief light stimulus (sequentially, the first afterimage is referred to as a "Hering afterimage", the second as a "Purkinje afterimage"). The Hess afterimage is defined as a physiological illusion. There are also several surgical instruments that are named after him.

Alexander_Ellinger

Alexander Ellinger (17 April 1870 in Frankfurt am Main – 26 July 1923 in Frankfurt am Main) was a German chemist and pharmacologist.
From 1887 he studied chemistry at the University of Berlin under August Wilhelm von Hofmann and at the University of Bonn as a pupil of August Kekulé. Afterwards, he studied medicine at the University of Munich, followed by work as an assistant in the institute of pharmacology at the University of Strasbourg. In 1897 he became an assistant to Max Jaffé in the laboratory of medicinal chemistry and experimental pharmacology at the University of Königsberg. In 1914 he was appointed professor of pharmacology at the newly established University of Frankfurt.He is remembered for his extensive biochemical research of several amino acids, especially tryptophan. In 1904 he isolated kynurenic acid from the urine of dogs that had been fed tryptophan. His other work included studies on the water exchange between body tissues and blood, on the formation on lymph, and with chemist Karl Spiro, he conducted investigations of blood coagulation.

Ricciotto_Canudo

Ricciotto Canudo (French: [kanydo]; 2 January 1877, Gioia del Colle – 10 November 1923, Paris) was an early Italian film theoretician who lived primarily in France. In 1913 he published a bimonthly avant-garde magazine entitled Montjoie!, promoting Cubism in particular. Involved in numerous movements yet confined to none, Canudo exuded seemingly boundless energy. He ventured into poetry, penned novels (pioneering a style emphasizing interpersonal psychology, which he dubbed sinestismo), and established open-air theatre in southern France. As an art critic, he unearthed talents like Chagall, curating a Chagall exhibition in 1914. In that same year, alongside Blaise Cendrars, he issued a call for foreigners residing in France to enlist in the French army. Among the 80,000 who responded was Canudo himself.He saw cinema as "plastic art in motion", and gave cinema the label "the Sixth Art", later changed to "the Seventh Art", still current in French, Italian, and Spanish conceptions of art, among others. Canudo subsequently added dance as a precursor to the sixth—a third rhythmic art with music and poetry—making cinema the seventh art.Canudo is often regarded as the inaugural aesthetician of cinema, thus making his "Manifesto" pertinent for an English-speaking readership. Several of Canudo's concepts found resonance with two prominent early French film experimenters—Jean Epstein and Abel Gance.

Rosita_Mauri

María Isabel Amada Antonia Rosa Mauri Segura or Roseta Mauri y Segura (15 September 1850 – 3 December 1923) was a Spanish dancer and ballet teacher. Her year of birth has also been quoted as between 1849 and 1856. A prima ballerina of international reputation, she was depicted frequently by artists, sculptors and photographers and was also the subject of several poetic tributes.

Gerónimo_Giménez

Gerónimo Giménez y Bellido (10 October 1854 – 19 February 1923) was a Spanish conductor and composer, who dedicated his career to writing zarzuelas, such as La tempranica and La boda de Luis Alonso. He preferred to spell his first name with a "G", even though his name at birth officially began with a "J".
Written in Spanish, a very comprehensive biographical exposition by Ascensión García de las Mozas may be found at the Universidad de Cádiz institutional repository of Research and Learning Objects (RODIN)

Louis_Mekarski

Louis Mékarski (in Polish Ludwik Mękarski) (1843, Clermont-Ferrand, France – 1923) was a French engineer and inventor of Polish origin. In the 1870s he invented the so-called Mekarski system of compressed-air powered trams which was used in several cities of France and USA as alternative to horse-powered and steam-powered trams.

Émile_Bergerat

Émile Bergerat (29 April 1845 – 13 October 1923) was a French poet, playwright and essayist. He used the pseudonyms l'Homme masqué (the masked man), Caliban and Ariel (the latter two drawn from The Tempest by William Shakespeare). A library in Neuilly-sur-Seine opposite his flat bears his name.
