Task: Question Generation
Input (English): Passage: Kertész emigrated to Paris in September 1925, leaving behind his mother, his unofficial fiancée Elizabeth, both brothers, and his uncle Hoffman, who died shortly afterward. Jenő later emigrated to Argentina. Elizabeth Kertész remained until her future husband was well enough established in Paris that they could marry. Kertész was among numerous Hungarian artists who emigrated during these decades, including François Kollar, Robert Capa, Emeric Fehér, Brassaï, and Julia Bathory. Man Ray, Germaine Krull and Lucien Aigner also emigrated to Paris during this period.
Initially Kertész took on commissioned work for several European magazines, gaining publication of his work in Germany, France, Italy and Great Britain. Soon after arriving in Paris, Kertész changed his first name to André, which he kept for the rest of his life. In Paris he found critical and commercial success.  In 1927 Kertész was the first photographer to have a one-man exhibition; Jan Slivinsky presented 30 of his photographs at the "Sacre du Printemps Gallery". Kertész had become connected with members of the growing Dada movement. Paul Dermée dubbed him "Brother Seer" and "Brother Seeing Eye" during his first solo exhibit, alluding to a medieval monastery where all the monks were blind bar one. Over the next years, Kertész was featured in both solo exhibits and group shows. In 1932 at the Julien Levy Gallery in New York, the price of Kertész's proofs was set at US$20 ($ 367 in 2019), a large sum of money during the Great Depression.Kertész and other Hungarian artists formed a synergistic circle; he was featured in exhibits with some of them later in his life.  Visiting his sculptor friends, he was fascinated by the Cubism movement.  He created photo portraits of painters Piet Mondrian and Marc Chagall, the writer Colette, and film-maker Sergei Eisenstein. In 1928, Kertész switched from using plate-glass cameras to a Leica. This period of work was one of his most productive; he was photographing daily, with work divided between magazine commissions through the late 1920s and his personal pieces. In 1930, at the Exposition Coloniale in Paris, Kertész was awarded a silver medal for services to photography.Kertész was published in French magazines such as Vu and Art et Médecine, for which his work was used for numerous covers. His greatest journalistic collaboration was with  Lucien Vogel, the French editor and publisher of Vu.  Vogel published his work as photo essays, letting Kertész report on various subjects through images. The photographer was intrigued with the variety of topics assigned by Vogel.
