to Russia via Switzerland and Sweden. His writing in The Blue Rider Almanac and the treatise "On the Spiritual in Art" (which was released in 1910) were both a defence and promotion of abstract art and an affirmation that all forms of art were equally capable of reaching a level of spirituality. He believed that colour could be used in a painting as something autonomous, apart from the visual description of an object or other form. These ideas had an almost-immediate international impact, particularly in the English-speaking world. As early as 1912, On the Spiritual in Art was reviewed by Michael Sadleir in the London-based Art News. Interest in Kandinsky grew apace when Sadleir published an English translation of On the Spiritual in Art in 1914. Extracts from the book were published that year in Percy Wyndham Lewis's periodical Blast, and Alfred Orage's weekly cultural newspaper The New Age. Kandinsky had received some notice earlier in Britain, however; in 1910, he participated in the Allied Artists' Exhibition (organised by Frank Rutter) at London's Royal Albert Hall. This resulted in his work being singled out for praise in a review of that show by the artist Spencer Frederick Gore in The Art News. Sadleir's interest in Kandinsky also led to Kandinsky's first works entering a British art collection; Sadleir's father, Michael Sadler, acquired several wood-prints and the abstract painting Fragment for Composition VII in 1913 following a visit by father and son to meet Kandinsky in Munich that year. These works were displayed in Leeds, either in the university or the premises of the Leeds Arts Club, between 1913 and 1923. Return to Russia (1914–1921) In 1916, he met Nina Andreevskaya (1899–1980), whom he married on 11 February 1917. From 1918 to 1921, Kandinsky was involved in the cultural politics of Russia and collaborated in art education and museum reform. He painted little during this period, but devoted his time to artistic teaching, with a program based on form and colour analysis; he also helped organize the Institute of Artistic Culture in Moscow of which he was the first director. His spiritual, expressionistic view of art was ultimately rejected by the radical members of the institute as too individualistic and bourgeois. In 1921, Kandinsky was invited to go to Germany to attend the Bauhaus of Weimar by its founder, architect Walter Gropius. Back in Germany and the Bauhaus (1922–1933) In May
