Question: The author of the book Pedagogical Sketchbook collaborated with what Russian painter?
Context: Pedagogical Sketchbook is a book by Paul Klee.  It is based on his extensive lectures on visual form at Bauhaus Staatliche Art School where he was a teacher in between 1921-1931. Andrei Drevin (Russian: Андрей Александрович Древин ; 26 August 1921 — 7 April 1996) was a Russian sculptor.  His parents were prominent Russian painter Nadezhda Udaltsova and Latvian painter Aleksandr Drevin. Michael Vasilyevich Matyushin (Russian: Михаил Васильевич Матюшин ; 1861 in Nizhny Novgorod – 14 October 1934 in Leningrad) was a Russian painter and composer, leading member of the Russian avant-garde.  In 1910–1913 Matyushin and his wife Elena Guro (1877–1913) were key members of the Union of the Youth, an association of Russian Futurists.  Matyushin, a professional musician and amateur painter, studied physiology of human senses and developed his own concept of the fourth dimension connecting visual and musical arts, a theory that he put to practice in the classrooms of Leningrad Workshop of Vkhutein and INHUK (1918–1934) and summarized in his 1932 "Reference of Colour" (Cправочник по цвету). Matyushin conducted experiments at his Visiology Center (Zorved) to demonstrate that expanding visual sensitivity from retinian optical centers would enable the discovery of "new organic substance and rhythm in the apprehension of space."  He tried to teach himself and his students to see with both eyes, each independently, and to widen the field of their vision.  He describes some of his work and ideas in a long essay titled "An Artist's Experience of the New Space." Paul Klee (] ; 18 December 1879 – 29 June 1940) was a Swiss-German artist.  His highly individual style was influenced by movements in art that included Expressionism, Cubism, and Surrealism.  Klee was a natural draftsman who experimented with and eventually deeply explored color theory, writing about it extensively; his lectures "Writings on Form and Design Theory" ("Schriften zur Form und Gestaltungslehre"), published in English as the "Paul Klee Notebooks", are held to be as important for modern art as Leonardo da Vinci's "A Treatise on Painting" for the Renaissance.  He and his colleague, Russian painter Wassily Kandinsky, both taught at the Bauhaus school of art, design and architecture.  His works reflect his dry humor and his sometimes childlike perspective, his personal moods and beliefs, and his musicality. Marie Bronislava Vorobyeva-Stebelska (Russian: Мария Брониславовна Воробьёва-Стебельская ; 1892 – 4 May 1984), also known as Marevna, was a 20th century, Russian-born painter known for her work with Cubism and Pointillism.  She is internationally known for convincingly combining elements of cubism (called by her "Dimensionalism") with pointillism and – through the use of the Golden Ratio for laying out paintings – structure.  She tends to be accredited with having been the first female cubist painter.  Though having lived the greater part of her life abroad – her formative years as a cubist painter in France and her mature years in England –, she is often referred to as a "Russian painter".  From her relationship with the Mexican cubist painter and later muralist Diego Rivera in Paris she had a daughter, Marika Rivera (1919-2010), who herself went on to become a professional dancer and film actress. Mikhail Shibanov (Russian: Михаил Шибанов ) was a Russian painter active during the 1780s; a portrait of Count Alexander Dmitriev-Mamonov of which he is known to be the author dates to about this time.  Shibanov was a serf of Prince Grigory Potemkin; his date of birth is unknown.  Two of his genre scenes are held at the Tretyakov Gallery in Moscow; the above-mentioned portrait is in the Russian Museum now. Filipp Andreevich Malyavin (Russian: Филипп Андреевич Малявин ) (October 22, 1869, Kazanki (Julian calendar: October 10) – December 23, 1940, Nice, France) was a Russian painter and draftsman.  Trained in icon-painting as well as having studied under the great Russian realist painter Ilya Repin, Malyavin is unusual among the Russian artists of the time for having a peasant background.  It is possibly due to this that his paintings often depict peasant life, and his most famous work, "Whirlwind", shows peasant women dancing. Mikhail Nikolayevich Romadin (Russian: Михаил Николаевич Ромадин ) (12 April 1940 – 3 January 2012) was a Russian painter, book illustrator, movie art designer and theater artist.  He graduated from the All-Union State Institute of Cinematography.  He is a third generation artist; his grandfather M.A. Romadin was a primitive style painter and his father, N.M. Romadin, was a landscape artist. Igor Petrovich Ivanov (Russian: Игорь Петрович Иванов ) (1923–1992) was a Soviet pedagogue, initiator and founder of the "social-pedagogical youth movement" known in Russia as the Communard movement.  He was a member of the Soviet Academy of Pedagogy, full professor of the Herzen Pedagogical State University, author of several books, laureate of the Makarenko Prize named after early Soviet educator Anton Makarenko.  Russian scholars consider Ivanov to be a creator of the "Communard methodology" or, as the author himself called it, the Collective Creative Deeds methodology (commonly referred to as "Metodologiya Kollektivnich Tvorcheskich del (KTD)" in Russian pedagogical literature), founder of the "pedagogy of partnership", which is also named "collective creative pedagogy" and "pedagogy of social creativity".  Ivanov's scholarly works continued the development of Creative Pedagogy. Ilya Zinovyevich Gordon (Russian: Илья Зиновьевич Гордон ; 15 December [O.S. 2 December] 1907 in Zelenopol – 28 February 1989 in Moscow), better known as Elye Gordon (Yiddish: אלי גאָרדאָן‎ ), was a Soviet Yiddish author.  He was born in Zelenopol, a Jewish agricultural colony in Russia near Yekaterinoslav, now in (Ukraine), but grew up in an orphanage in Berdyansk.  Gordon studied at the Yiddish language departments ("rabfak") of the Odessa Pedagogical Institute, then Moscow Pedagogical Institute.  As a volunteer for the Red Army during World War II, Gordon was twice decorated with the Order of the Red Banner.  Wartime themes would also figure in his literary work.
