Task: Question Answering
Input (English): Passage: Toward the end of 1961, Kertész broke his contract to Condé Nast Publishing after a minor dispute, and started doing his own work again.  This later period of his life is often referred to as the "International period", when he gained worldwide recognition and his photos were exhibited in many countries. In 1962 his work was exhibited in Venice; in 1963, he was one of the invited artists of the IV Mostra Biennale Internazionale della Fotografia there and he was awarded a gold medal for his dedication to the photographic industry.  Later in 1963, his work was shown in Paris at the Bibliothèque nationale de France. He later visited Argentina to see his younger brother Jenő for the first time in years.  Kertész experimented with color photographs, but only produced a few.
In 1964, soon after John Szarkowski became the photography director at the Museum of Modern Art, he featured Kertész in a solo show. With his work critically acclaimed, Kertész gained recognition in the photographic world as an important artist. 
The work of Kertész was featured in numerous exhibitions throughout the world in his later life, even into his early nineties. Due to his newfound success, in 1965 Kertész was appointed as a member of the American Society of Media Photographers.
His awards rapidly accumulated: 
1974, Guggenheim Fellowship;
1974, Commander of the French Ordre des Arts et des Lettres;
1977, Mayor's Award of Honor for Arts and Culture in New York,
1980 the Medal of the City of Paris, and the first Annual Award of the Association of International Photography Art Dealers in New York; and
1981, honorary Doctorate of Fine Arts from Bard College, and the New York Mayor's Award of Honor for Arts and Culture that year.During this period, Kertész produced a number of new books.  He was able to recover some of the negatives he had left in France decades before.
Despite his successes, Kertész still felt unrecognised as a photographer. His last years were spent travelling to various locations around the globe for his exhibitions, especially Japan, and rekindling friendships with other artists. To deal with the loss of his wife in 1977, Kertész fell back on his new network of friends, often visiting them to talk. By this time, he was said to have learned basic English and talked in what his friends called "Kertészian", a mixture of Hungarian, English and French.In 1979, the Polaroid Corporation gave him one of their new SX-70 cameras, which he experimented with into the 1980s. Still growing in fame, Kertész was granted the National Grand Prize of Photography in Paris in 1982, as well as the 21st Annual George Washington Award from the American Hungarian Foundation the same year.
