Answer the following question: Found the following article online, use it to answer the question: What is the original name of the person who was involved with many young immigrant artists and the Dada movement?  André Kertész (French: [kɛʁtɛs]; 2 July 1894 – 28 September 1985), born Kertész Andor, was a Hungarian-born photographer known for his groundbreaking contributions to photographic composition and the photo essay. In the early years of his career, his then-unorthodox camera angles and style prevented his work from gaining wider recognition. Kertész never felt that he had gained the worldwide recognition he deserved. Today he is considered one of the seminal figures of photojournalism.Expected by his family to work as a stockbroker, Kertész pursued photography independently as an autodidact, and his early work was published primarily in magazines, a major market in those years. This continued until much later in his life, when Kertész stopped accepting commissions. He served briefly in World War I and moved to Paris in 1925, then the artistic capital of the world, against the wishes of his family. In Paris he worked for France's first illustrated magazine called VU. Involved with many young immigrant artists and the Dada movement, he achieved critical and commercial success. Due to German persecution of the Jews and the threat of World War II, Kertész decided to emigrate to the United States in 1936, where he had to rebuild his reputation through commissioned work. In the 1940s and 1950s, he stopped working for magazines and began to achieve greater international success. His career is generally divided into four periods, based on where he was working and his work was most prominently known.  They are called the Hungarian period, the French period, the American period and, toward the end of his life, the International period.
