1973 deaths

Olga Maturana Espinosa (October 10, 1906 – July 16, 1973) was a Chilean politician born in Santiago. Maturana worked as Councillor of Pichilemu in 1950, and became the first female Mayor of Pichilemu in 1951.

Camilo Mori Serrano (September 24, 1896 – December 7, 1973) was a Chilean painter and a founder of the Grupo Montparnasse.
The son of an Italian immigrant, Camilo Mori entered the "Escuela de Bellas Artes" (School of Fine Arts) at the University of Chile in 1914 and studied under masters Juan Francisco González, Richón Brunet and Alberto Valenzuela Llanos. In 1920, he was sent by the Chilean government to further his studies in Europe]
Over the next three years, Mori spent time in Rome and Paris. He joined the gathering of artists in the Montparnasse Quarter in Paris. There, his encounter with Pablo Picasso and Juan Gris greatly influenced his ideas of painting. However it was the influence of the works of Paul Cézanne that challenged Mori to move away from the Realism that marked his earlier work. He started experimenting with a variety of styles which later formed the basis of modern art. He exhibited in the Salon d'Automne of 1920 in Paris, where his "Circo de la Feria" received an honorable mention.
He returned to Chile and became one of the founding members of the Grupo Montparnasse, a key influence in the diffusion of the new European painting trends in Chile. In 1928 Camilo Mori was named director of the National Museum of Fine Arts (Spanish: Museo Nacional de Bellas Artes or MNBA). During his tenure in this post, he was responsible for many initiatives aimed at promoting art in Chile. In 1928, as an initiative to mitigate the closure of the School of Fine Arts, Mori was once again sent by the Chilean government to Europe, this time to direct the studies of a group of young painters known as the "Generation of 1928" (Spanish: Generacion del 28), which culminated in 26 of the most outstanding young Chilean artists being sent to study in Paris for five years.
Mori returned to Chile in 1933, where he accepted a position as professor of drawing and color at the Universidad de Chile, a post he retained for over 30 years. In 1937 he moved to the United States where he spent two years exploring some of the newest artistic trends of the time. He was placed in charge of supervising the decoration of, and created a mural for, the pavilion of Chile at the 1939 New York World's Fair.
For his contribution to Chilean art, in 1950 he received the National Prize of Art. His work was complex and multifaceted and moved through Post-Impressionism, Expressionism, Cubism and Surrealism, with the common trend among them being a prominent treatment of color.

Mortimer "Bud" Sprague (September 8, 1904 – April 25, 1973) was an American football player. He was elected to the College Football Hall of Fame in 1970.He was one of the eight children born to Minna and George Sprague, of the Oak Cliff neighborhood in Dallas, Texas. Bud's father George served on the Dallas City Council and as the Mayor of Dallas from 1937 to 1939. Bud originally played on University of Texas' varsity football team, and later transferred to the United States Military Academy to play out his eligibility for the Army Black Knights. Eventually Bud settled in the Greenwich Village neighborhood of Manhattan and made his fortune in maritime insurance. He named his son, Kurth Sprague, after his mentor.

Hilary J. Sandoval Jr. (January 29, 1930 – June 11, 1973) was an American businessman who served as Administrator of the Small Business Administration from 1969 to 1971.He died on June 11, 1973, in El Paso, Texas, from complications of brain surgeries at the age of 43.

Catherine Schleimer-Kill, née Kill (1884–1973), was a Luxembourg suffragist and women's rights activist. She was founder and secretary of the Action féminine.

Eugen Kahn (born 20 May 1887 in Stuttgart, Germany – died January 1973 in Houston, Texas) was a German psychiatrist. His "habilitation" supervisors were Emil Kraepelin and Ernst Rüdin.He argued Willenlos was a misnomer for the Haltlose, as the patients demonstrated plenty of "will" and simply lacked the ability to translate it into action.
He was the first Sterling Professor of Psychiatry and Chairman of the Department of Psychiatry at Yale 1930-1946.

Alfred Gottschalk (22 April 1894 – 4 October 1973) was a German biochemist who was a leading authority in glycoprotein research. During his career he wrote 216 research papers and reviews, and four

books.Gottschalk was born in Aachen, the third of four children to Benjamin and Rosa Gottschalk, who had Jewish heritage. He was raised Catholic. He choose to study medicine, from 1912 he attended the Universities of Munich, Freiburg im Breisgau and Bonn. During the war he served in the medical corps of the German Army. He completed his medical degree in 1920, graduating MD from the University of Bonn. He completed clinical work experience at the medical schools of Frankfurt am Main and Würzburg and physiology-biochemistry studies at Bonn, that led to his first publications, an award from the University of Madrid and an invitation to work at the Kaiser Wilhelm Institute for Experimental Therapy and Biochemistry with Carl Neuberg.
In 1923 he married Lisbeth Berta Orgler; together they had one son. They separated in 1950. Gottschalk left the Kaiser Wilhelm Institute for Biochemistry in 1926 to become Director of the Biochemical Department at the General Hospital in Stettin. He left the hospital in 1934 following upheaval in Nazi Germany and entered private practice, left for England in the spring of 1939, and on to Melbourne in July. He was offered a position as a biochemist by Charles Kellaway, director of the Walter and Eliza Hall Institute (WEHI). He initially worked with yeast enzymes and fermentation, but in 1947 he joined the virus department, where he worked with Frank Macfarlane Burnet. He also taught biochemistry and organic chemistry at the Melbourne Technical College and later at the University of Melbourne. In 1945 he became a naturalized British citizen. In 1949 he received a DSc from the University of Melbourne.
He was elected a Fellow of the Australian Academy of Science in 1954. He discovered viral neuraminidase there in 1957. As Burnet stated: “In the world of biochemistry the most important contribution of the Walter and Eliza Hall Institute is regarded as Gottschalk’s discovery of the structure of the sialic acids and his recognition that an enzyme which I had characterised biologically was chemically a neuraminidase. Gottschalk’s work was masterly and it was definitive.”On his retirement in 1959, he was invited by his friend and former WEHI colleague Frank Fenner to research at the John Curtin School of Medical Research at the Australian National University. He returned to Germany in 1963, where he was appointed Guest-Professor at the Max Planck Institute for Virus Research in Tübingen. He continued active research and for his contributions to science was elected to the Fellowship of the American Association for the Advancement of Science in 1967 and received an honorary doctorate from the University of Münster (MD) in 1969.
He died in Tübingen on 4 October 1973. The Gottschalk Medal for medical research awarded by the Australian Academy of Science is named in his honour.

Jean Bosler (24 March 1878, Angers – 25 September 1973, Marseille) was a French astronomer and author of several books.
Recruited by Deslandres as an astronomer at l’observatoire de Paris, Bosler discovered in 1908 in the spectrum of Comet Morehouse the spectral lines of ionized nitrogen, which was the first evidence of that element in comets. Much of his research was on the physical properties and orbits of comets. He made a report on progress in astrophysics in the United States for the 1910 annual report of the Smithsonian Institution. In 1912, he showed in his doctoral dissertation (supervised by Henri Poincaré) that the Sun’s magnetic field, by means of the intermediary of the solar wind, explains many aspects of cometary tails, the aurora borealis and aurora australis, solar storms and telluric currents. During a solar eclipse in 1914, Bosler observed in the corona a spectral band “nouvelle, intense et unique” which he suggested was spectral evidence for coronium; however, in the 1930s subsequent research showed that the cause was a highly ionized form of iron. In 1916, he published an analysis of the circular form of lunar craters as caused by the impact of meteors.
In 1923 Bosler was named director of Marseille Observatory, a post he occupied until his retirement in 1948. Simultaneously with his directorship, he taught at the University of Marseille from 1923 to 1948. Bosler made important contributions to the theory of the evolution of stars and published the first textbook in French that dealt with the then recent discoveries of Hubble and the work on optical phenomena of such physicists as Michelson, Fabry and Perot.
Bosler won the Prix Jules Janssen in 1911 from the Société astronomique de France, the French astronomical society, and the Prix Lalande from l'Académie des sciences in 1913.
He came from the French branch of the Hessian family Boßler.Books
