1935 deaths

Wilhelm Kolle (born 2 November 1868 in Lerbach near Osterode am Harz, died 10 May 1935) was a German bacteriologist and hygienist. He served as the second director of the Royal Institute for Experimental Therapy, succeeding its founder, the Nobel laureate Paul Ehrlich. He was also the original author, with Heinrich Hetsch, of the famous book Experimental Bacteriology, one of the most authoritative works in microbiology in the first half of the 20th century.
Following studies of medicine at the universities of Göttingen, Halle and Würzburg, he became an assistant to Robert Koch at the Institut für Infektionskrankheiten (Institute for Infectious Diseases) in Berlin (1893–97). In 1897–98 he performed research of rinderpest and leprosy in South Africa, and in 1900, on behalf of the Egyptian government, studied rinderpest in Sudan.
In 1901 he became departmental head at the Institut für Infektionskrankheiten, followed by an appointment as professor of hygiene and bacteriology at the University of Bern (1906). As a military physician and hygienist during World War I, he was highly successful in vaccination against diphtheria and cholera. In 1917, he became director of the Royal Institute for Experimental Therapy and of the Georg Speyer House in Frankfurt am Main.
Kolle made numerous contributions in the fields of serology, microbiology and chemotherapy. He is credited with the development of an anti-meningococcus serum, as well as a vaccine against rinderpest. He introduced an improved Salvarsan preparation for treatment of syphilis, and in 1896 developed a heat-inactivated cholera vaccine that was used extensively during the 20th century.He was the father of the painter Helmut Kolle (1899–1931).

Philippe Dautzenberg (20 December 1849, in Ixelles, Brussels – 9 May 1935, in Paris) was a Belgian malacologist, a biologist who specializes in the branch of invertebrate zoology that deals with mollusks. He was an amateur and autodidact, who was actually the owner of a carpet and soft furnishings factory. He was also a devoted family man with 12 children.
He assembled, thanks to his many connections all over the world, a large part of the shell collection of the Royal Belgian Institute of Natural Sciences, which consists of 9,000,000 specimens and is one of the three largest shell collections in the world.
He was a participant in the scientific surveys of Prince Albert I of Monaco and the author of 210 published works (between 1881 and 1937 (post mortem) ) in the field of malacology. He described 1895 new taxa. He collected shells from an early age, resulting in his personal collection of about 4.5 million specimens, relating to 33,000 Recent taxa and 7,000 fossil species. He referenced 82,000 specimens on filing cards.He belonged to several scientific societies in Belgium and France, including the Société royale malacologique de Belgique, Société linnéenne de Lyon (1921–1935) and the Société d'histoire naturelle de l'Afrique du Nord (1926). In 1892 he was named president of the Société zoologique de France.

Friedrich Carl Duisberg (29 September 1861 – 19 March 1935) was a German chemist and industrialist.

Therese Elisabeth Alexandra Förster-Nietzsche (10 July 1846 – 8 November 1935) was the sister of philosopher Friedrich Nietzsche and the creator of the Nietzsche Archive in 1894.
Förster-Nietzsche was two years younger than her brother. Their father was a Lutheran pastor in the German village of Röcken bei Lützen. The two children were close during their childhood and early adult years. However, they grew apart in 1885 when Elisabeth married Bernhard Förster, a former high school teacher who had become a prominent German nationalist and antisemite. Friedrich Nietzsche did not attend their wedding.
Förster-Nietzsche and her husband created an unsuccessful colony, Nueva Germania, in Paraguay in 1887. Her husband killed himself in 1889. Förster-Nietzsche continued to run the colony until she returned to Germany in 1893 where she found her brother to be an invalid whose published writings were beginning to be read and discussed throughout Europe. Adolf Hitler attended her funeral in 1935.In the 1950s it was claimed by Nietzsche's new editors and translators such as Walter Kaufmann that Nietzsche's work had been falsely edited by Elisabeth to highlight racist and eugenicist themes, but this account has been the subject of debate in recent scholarship. An alternative theory exonerates Elisabeth and places the distortion of Nietzsche's works in the hands of the Nazis themselves.

Léonce Joseph Perret (14 March 1880 – 12 August 1935) was a prolific and innovative French film actor, director and producer. He also worked as a stage actor and director. Often described as avant-garde for his unorthodox directing methods, Perret introduced innovative camera, lighting and film scoring techniques to French cinema.
Perret began his career as a relatively undistinguished stage actor. He was recruited to the film industry by the Gaumont Film Company. His numerous short films gained significant accolade in French cinematography. Until his emigration to the United States in 1917, he was a fixture of the Gaumont Film Company. On American soil, he produced several popular films, the most notable being Lest We Forget (N'oublions jamais) in 1918.
After returning to France, he directed the successful Koenigsmark in 1923. His film Madame Sans-Gêne (1925), starring Gloria Swanson, was the first joint Franco-American film production. In addition, Perret collaborated with many of the French and American idols of his generation such as Abel Gance, Gloria Swanson, Gaby Morlay, René Cresté, Arletty, Suzanne Grandais, Mae Murray, and Huguette Duflos.

Hugo Junkers (3 February 1859 – 3 February 1935) was a German aircraft engineer and aircraft designer who pioneered the design of all-metal airplanes and flying wings. His company, Junkers Flugzeug- und Motorenwerke AG (Junkers Aircraft and Motor Works), was one of the mainstays of the German aircraft industry in the years between World War I and World War II. His multi-engined, all-metal passenger- and freight planes helped establish airlines in Germany and around the world.
In addition to aircraft, Junkers also built both diesel and petrol engines and held various thermodynamic and metallurgical patents. He was also one of the main sponsors of the Bauhaus movement and facilitated the move of the Bauhaus from Weimar to Dessau (where his factory was situated) in 1925.
Amongst the highlights of his career were the Junkers J 1 of 1915, the world's first practical all-metal aircraft, incorporating a cantilever wing design with virtually no external bracing, the Junkers F 13 of 1919 (the world's first all-metal passenger aircraft), the Junkers W 33 (which made the first successful heavier-than-air east-to-west crossing of the Atlantic Ocean), the Junkers G.38 "flying wing", and the Junkers Ju 52, affectionately nicknamed "Tante Ju", one of the most famous airliners of the 1930s.
When the Nazis came into power in 1933, they requested Junkers and his businesses aid in the German re-armament. When Junkers declined, the Nazis placed him under house arrest in 1934 and eventually seized control of his patents and company. He died the following year. Under Nazi control, his company produced some of the most successful German warplanes of the Second World War.

Lieven Gevaert (28 May 1868 – 2 February 1935) was a Flemish industrialist. His father died when he was only three years old. He started his career in the company he founded together with his mother in 1889, which produced photographic paper according to traditional methods. In 1894, he founded the company Gevaert & Co, which in 1920, was transformed to N.V Gevaert Photo-producten, merged in 1964 with Agfa AG to become Gevaert-Agfa NV and later Agfa-Gevaert NV.
Already at an early age, he felt socially responsible and wanted to advance the status of Dutch in Belgium. His personal ideas were strongly influenced by the social encyclical Rerum novarum (1891) and the writings of Lodewijk De Raet. He supported several Flemish initiatives as a manager, but stayed outside politics. His main objectives were the introduction of Dutch as a business language, and the foundation of a sound Dutch-speaking education as a means to establish a Flemish elite. In 1926, when the Vlaamsch Handelsverbond (Vlaams Economisch Verbond, VEV) was founded, Gevaert was its first chairman. Later, he founded the Sint-Lievenscollege in Antwerp, where he lived on Belgiëlei.

André-Gustave Citroën (French: [ɑ̃dʁe ɡystav sitʁɔɛn]; 5 February 1878 – 3 July 1935) was a French industrialist and the founder of French automaker Citroën. He is also remembered for his application of double helical gears.

Eugene "Zim" Zimmerman (May 26, 1862 – March 26, 1935) was a Swiss-American cartoonist.

Carlos Gardel (born Charles Romuald Gardès; 11 December 1890 – 24 June 1935) was a French-born Argentine singer, songwriter, composer and actor, and the most prominent figure in the history of tango. He was one of the most influential interpreters of world popular music in the first half of the 20th century. Gardel is the most famous popular tango singer of all time and is recognized throughout the world. Described variously as a baritone or tenor because of his wide vocal range, he was known for his rich voice and dramatic phrasing. Together with lyricist and long-time collaborator Alfredo Le Pera, Gardel wrote several classic tangos.
Gardel died in an airplane crash at the height of his career, becoming an archetypal tragic hero mourned throughout Latin America. For many, Gardel embodies the soul of the tango style. He is commonly referred to as "Carlitos", "El Zorzal" ("The Song thrush"), "The King of Tango", "El Mago" (The Wizard), "El Morocho del Abasto" (The Brunette boy from Abasto), and ironically "El Mudo" (The Mute).
In 1967, a controversial theory was published by Uruguayan writer Erasmo Silva Cabrera, asserting that Gardel was born in Tacuarembó, Uruguay. Other authors expanded upon this theory, and a museum to Gardel was established in Tacuarembó. But Gardel's friends and family all knew him as a French immigrant from Toulouse. Scholarly researchers analyzed the contradictory evidence, especially French birth and baptismal records, and confirmed his birthplace as Toulouse.
