Query: What is Sergey Mikhaylovich Prokudin-Gorsky best known for?
Sergey Mikhaylovich Prokudin-Gorsky (, ;  – September 27, 1944) was a Russian chemist and photographer. He is best known for his pioneering work in colour photography and his effort to document early 20th-century Russia.
Another very notable practitioner was Adolf Miethe, with whom Prokudin-Gorsky studied in Germany in 1902. Miethe was a photochemist who greatly improved the panchromatic characteristics of the black-and-white photographic materials suitable for use with this method of color photography. He presented projected color photographs to the German Imperial Family in 1902 and was exhibiting them to the general public in 1903, when they also began to appear in periodicals and books. Miethe took the first known aerial color photographs, from a hot air balloon, in 1906.
Tarkovsky's films include "Ivan's Childhood" (1962), "Andrei Rublev" (1966), "Solaris" (1972), "Mirror" (1975), and "Stalker" (1979). He directed the first five of his seven feature films in the Soviet Union; his last two films, "Nostalghia" (1983) and "The Sacrifice" (1986), were produced in Italy and Sweden, respectively. The films "Andrei Rublev", "Solaris", "Mirror", and "Stalker" are regularly listed among the greatest films of all time.
Following the collapse of the Soviet Union, Piotrovsky advocated the opening of the Hermitage collections to the wider world, which resulted in the establishment of the Hermitage Rooms in Somerset House, Hermitage Amsterdam and the Guggenheim Hermitage Museum. His tenure was not entirely free of scandals, however. After the museum announced in July 2006 that 221 minor items, including jewelry, Orthodox icons, silverware and richly enameled objects, had been stolen by one of the museum officials, there were calls for Piotrovsky's resignation.
In 1965, he directed the film "Andrei Rublev" about the life of Andrei Rublev, the fifteenth-century Russian icon painter. "Andrei Rublev" was not, except for a single screening in Moscow in 1966, immediately released after completion due to problems with Soviet authorities. Tarkovsky had to cut the film several times, resulting in several different versions of varying lengths. The film was widely released in the Soviet Union in a cut version in 1971.
Tarkovsky's first feature film was "Ivan's Childhood" in 1962. He then directed "Andrei Rublev" in 1966, "Solaris" in 1972, "Mirror" in 1975 and "Stalker" in 1979. The documentary "Voyage in Time" was produced in Italy in 1982, as was "Nostalghia" in 1983. His last film "The Sacrifice" was produced in Sweden in 1986. Tarkovsky was personally involved in writing the screenplays for all his films, sometimes with a cowriter. Tarkovsky once said that a director who realizes somebody else's screenplay without being involved in it becomes a mere illustrator, resulting in dead and monotonous films.
Ivan Petrovich Pavlov (; 27 February 1936) was a Russian physiologist known primarily for his work in classical conditioning.
Pavlov won the Nobel Prize for Physiology or Medicine in 1904, becoming the first Russian Nobel laureate. A survey in the "Review of General Psychology", published in 2002, ranked Pavlov as the 24th most cited psychologist of the 20th century. Pavlov's principles of classical conditioning have been found to operate across a variety of behavior therapies and in experimental and clinical settings, such as educational classrooms and even reducing phobias with systematic desensitization.
As the Polish–Soviet War grew in intensity, in late April 1920 the Red Army of Russia's new Soviet regime pushed back Polish forces and invaded Poland. Subsequently, Sikorski successfully defended Mozyr and Kalenkowicze until 29 June, but later failed to hold the Brest fortress, although he defended it long enough to allow the Polish forces in the region to retreat in an orderly manner. On 6 August he was named the commander of the newly formed Polish 5th Army, which was tasked with holding the front to the north of Modlin, between Narew and Wkra rivers. He distinguished himself commanding the 5th Army on the Lower Vistula front during the Battle of Warsaw. At that time Soviet forces, expecting an easy final victory, were surprised and crippled by the Polish counter-attack. During that battle (sometimes referred to as "the Miracle at the Vistula") Sikorski stopped the Bolshevik advance north of Warsaw and gave Piłsudski, the Polish commander-in-chief, the time he needed for his counter-offensive; beginning with the 15 August his forces successfully engaged the Soviet 5th and 15th Armies. After the Battle of Warsaw, from 30 August, Sikorski commanded the 3rd Army. His forces took Pińsk, and fought during the latter stages of the Battle of Lwów and the Battle of Zamość, and then after Battle of Niemen advanced with his forces toward Latvia and deep into Belarus. The Poles defeated the Soviets, and the Polish–Soviet Treaty of Riga (March 1921) gave Poland substantial areas of Belarus and Ukraine's (Kresy). Sikorski's fame was enhanced as he became known to the Polish public as one of the heroes of the Polish–Soviet War. He also kept publishing military science articles during the war itself. For his valorous achievements Sikorski was promoted to divisional general on 28 February 1921, and was awarded Poland's highest military decoration, the order of Virtuti Militari, on 15 March that year.
Tarkovsky's first feature film was "Ivan's Childhood" in 1962. He had inherited the film from director Eduard Abalov, who had to abort the project. The film earned Tarkovsky international acclaim and won the Golden Lion award at the Venice Film Festival in the year 1962. In the same year, on 30 September, his first son Arseny (called Senka in Tarkovsky's diaries) Tarkovsky was born.
Having attained the rank of major, Pavlichenko never returned to combat but became an instructor and trained Soviet snipers until the war's end. In 1943, she was awarded the Gold Star of the Hero of the Soviet Union, and was commemorated on a Soviet postage stamp.
Yurii (or Yuri) Vladimirovich Egorov (Юрий Владимирович Егоров, born 14 July 1938 in Moscow, died October 2018 in Toulouse) was a Russian-Soviet mathematician who specializes in differential equations.
On 10 June 1948, Tamm headed a new group of theorists which included Andrei Sakharov, Vitaly Ginzburg, S.Z. Belenky and Romanov. They followed up Sakharov's ideas for a new thermonuclear weapon and went to KB-11 (now the All-Russian Scientific Research Institute of Experimental Physics) in the closed city of Sarov, Nizhny Novgorod. He started as a junior researcher, then senior, then head of department. In 1952, he received a degree in Physical and Mathematical Sciences with a thesis on kinetic processes of neutrons. This work on neutrons and efficiency continued, along with calculations on nuclear reaction kinetics and energy release of the Soviet Union's first thermonuclear weapon, the RDS-6, tested in 1953; for this he was awarded the Stalin Prize, the first of several awards. He was a leading developer of the RDS-37 - the first Soviet two-stage thermonuclear weapon - most specifically concerned with the power output. Romanov transferred to the new Scientific Research Institute-1011 as head of the theoretical department in 1955. Two years later, his team had developed a new megatonne-yield bomb design. He gained a Ph.D. in Physical and Mathematical Sciences in 1958 and was appointed to professorship of theoretical physics in 1962.
Lyudmila Mikhailovna Pavlichenko (; 12 July 191610 October 1974) was a Soviet sniper in the Red Army during World War II, credited with 309 kills. She is regarded as one of the top military snipers of all time and the most successful female sniper in history.
He graduated from Moscow University in 1815. After a doctorate in medicine, and two years travelling in Europe to study science, he was given a chair in Moscow in 1821, in Agriculture, Mineralogy and Forestry. Subsequently he wrote textbooks in agriculture and chemistry, and lobbied for changed agricultural practices.Schelling appears as a kind of absentee grand master of a new higher order. The most popular university lecturer of the period, Professor Pavlov, was master of ceremonies, greeting students at the door of his lecture hall with his famous question: "You want to know about nature, but what is nature and what is knowledge?"
Mykola Leontovych specialised in a cappella choral music. He is remembered today mostly through the musical works he left behind, which include over 150 choral compositions. These range from artistic arrangements of folk songs, religious works (including his liturgy), cantatas, and choral compositions set to the words of various Ukrainian poets. His two most famous works are the choral miniatures "Schedryk" and "Dudaryk".
Le Corbusier had a short relationship with the Soviet Union, starting with his first trip to Moscow in 1928, and ending with the rejection of his proposal for the Palace of the Soviets in 1932. Nevertheless, the short-lived relationship had consequences that went beyond Le Corbusier’s time in the USSR. Before his trip to Moscow, Le Corbusier was already an influential figure within the Soviet field of architecture. In 1922, Moisei Ginzburg, founder of the Constructivist movement, published materials from Le Corbusier’s “Towards a New Architecture,” and in 1924 published his own book, similar to Le Corbusier’s, titled "Style and Epoch", which became to a central text to the Constructivist movement. Likewise, Corbusier’s projects were frequently published and analyzed as examples for the young generation of Soviet architects to use as inspiration. When Le Corbusier died in 1965, the official newspaper of the Soviet Union, Pravda, stated in its obituary, “Modern architecture has lost its greatest master.” This statement suggests the importance of Le Corbusier’s architecture and urbanism in the Soviet Union.
Hristo Prodanov () (February 24, 1943 - April 21, 1984) was a Bulgarian mountaineer. He was the first Bulgarian who climbed Mount Everest, doing it through the most difficult way - the West Ridge- as well as alone and without oxygen. He was the first person to climb Everest in April, when the weather conditions are generally too bad for an expedition. He died in a storm during the descent.
William Henry Fox Talbot FRS FRSE FRAS (; 11 February 180017 September 1877) was an English scientist, inventor and photography pioneer who invented the salted paper and calotype processes, precursors to photographic processes of the later 19th and 20th centuries. His work, in the 1840s on photomechanical reproduction, led to the creation of the photoglyphic engraving process, the precursor to photogravure. He was the holder of a controversial patent which affected the early development of commercial photography in Britain. He was also a noted photographer who contributed to the development of photography as an artistic medium. He published "The Pencil of Nature" (1844–46), which was illustrated with original salted paper prints from his calotype negatives, and made some important early photographs of Oxford, Paris, Reading, and York.
The successful debut of "Shchedryk" earnt Leontovych popularity among specialists and fans of choral music in Kiev. Leontovych's mentor-turned-coworker at the Kiev Conservatory, Boleslav Yavorsky, also positively evaluated his newly written works. During another concert, Leontovych's "Lehenda", set to a poem by Mykola Voronyi, gained great popularity.
The young doctor Ivan Pavlov wants to live life "honorably and humanely." The path of the scientist is difficult and thorny. The treasury department does not release funds for research nor give access to animals for experimental use and Pavlov has to buy them on his own savings. The experiments follow one another. Pavlov is pursuing his goal with passion and force. For his work on the physiology of digestion he is awarded the Nobel Prize. Pavlov paves the way for objective studies of brain function in higher animals. Zvantsev, the assistant of Pavlov is an idealist who has become an ideological opponent of the scientist-materialist, implores him not to interfere with the "sanctuary of the spirit", but Pavlov boldly ignores his opponents-obscurantists. The revolutionary 1917 year comes. Pavlov angrily rejects the proposal of an American agent to go abroad; he decides to forever remain with his people in his homeland.
Prokudin-Gorsky was born in Murom in the ancestral estate of Funikova Gora, in what is now Kirzhachsky District, Vladimir Oblast. His parents were of the Russian nobility, and the family had a long military history. They moved to Saint Petersburg, where Prokudin-Gorsky enrolled in Saint Petersburg State Institute of Technology to study chemistry under Dmitri Mendeleev. He also studied music and painting at the Imperial Academy of Arts.
In 1890, Prokudin-Gorsky married Anna Aleksandrovna Lavrova, and later the couple had two sons, Mikhail and Dmitri, and a daughter, Ekaterina. Anna was the daughter of the Russian industrialist Aleksandr Stepanovich Lavrov, an active member in the Imperial Russian Technical Society (IRTS). Prokudin-Gorsky subsequently became the director of the executive board of Lavrov's metal works near Saint Petersburg and remained so until the October Revolution. He also joined Russia's oldest photographic society, the photography section of the IRTS, presenting papers and lecturing on the science of photography. In 1901, he established a photography studio and laboratory in Saint Petersburg. In 1902, he traveled to Berlin and spent six weeks studying colour sensitization and three-colour photography with photochemistry professor Adolf Miethe, the most advanced practitioner in Germany at that time. Throughout the years, Prokudin-Gorsky's photographic work, publications and slide shows to other scientists and photographers in Russia, Germany and France earned him praise, and in 1906 he was elected the president of the IRTS photography section and editor of Russia's main photography journal, the "Fotograf-Liubitel". Gorsky was a member of the Royal Photographic Society between 1920 and 1932..
Perhaps Prokudin-Gorsky's best-known work during his lifetime was his color portrait of Leo Tolstoy, which was reproduced in various publications, on postcards, and as larger prints for framing. The fame from this photo and his earlier photos of Russia's nature and monuments earned him invitations to show his work to the Russian Grand Duke Michael Alexandrovich and Dowager Empress Maria Feodorovna in 1908, and to Tsar Nicholas II and his family in 1909. The Tsar enjoyed the demonstration, and, with his blessing, Prokudin-Gorsky got the permission and funding to document Russia in color. In the course of ten years, he was to make a collection of 10,000 photos. Prokudin-Gorsky considered the project his life's work and continued his photographic journeys through Russia until after the October Revolution. He was appointed to a new professorship under the new regime, but he left the country in August 1918. He still pursued scientific work in color photography, published papers in English photography journals and, together with his colleague S. O. Maksimovich, obtained patents in Germany, England, France and Italy.
On 30 August 2018, to commemorate what would have been his 155th birthday, Google released a Google Doodle celebrating him.
Prokudin-Gorsky was also acquainted with the use of Autochrome color plates, which did not require a special camera or projector. He was one of the favored few the Lumière Brothers introduced to their new product in 1906, the year before it went into commercial production. Autochrome plates were expensive and not sensitive enough for casual "snapshots" with a hand-held camera, but their use was simple and in expert hands they were capable of producing excellent results. They made color photography truly practical for advanced amateurs and led some pioneering users of color separation cameras to abandon their methods as outmoded, but Prokudin-Gorsky was not won over. No Autochromes by Prokudin-Gorsky are known to survive.
