Born in 1931, lives in Istanbul. In 1956 he graduates from Zeki Faik Izer’s atelier in IDGSA Painting Department. Besides Paris biennals in 1963-1965 he participated numerous international and national art activities, he opened so many solo exhibitions. His name became famous as a writer and lecturer. He was the first artist who improved and represented some western ideas such as; modernist, avangarde approach to pop art and specially postmodernism in Turkey.
He was also the first curator who attempt to organize an exhibition in Turkey; Avni Lifij’s exhibition in 1968 was the first example.
As having his own fiction world the artist not only assists Contemporary Turkish Art but also gives shape to its fate and it is seen that he is the one that impresses almost all artists of his generation and next generation about today’s Turkish Art. About this subject he expresses; “An artist gives referances, the effect is inevitable, not the method but the result is important.”
With his productive natural talent Altan proves that he has an endless, dynamic, energetic personality.
In his creations he appropriates an art understanding that coincidentally mixed incongrous elements such as; different texture, structure elements, materials, art view, light etc .. With clearer thoughts and ways from 1988 he developed coincidental mixing method to prove artistic space is made up of different concepts, backgrounds, edifices and logics that meet in extreme points.
He examined espas and has taken as the main course in his lectures. As a result of his researches on espas, rather than the historic way he clearly declarated that; “art meets from different ideas, logic, sources, structure and concepts”. After this conclusion he declerated his ideas (with the title of space in art) first time, front of academitions, at associated professorship lecture in 1970.
After that decleration Altan has improved a new international art feature on that allegation. He has coincidently made a unity from the different participands works such as landscape, plans, maps and the distric sketchs and at the end participants applyed the design with the alien materials. This method has been performed by totally different participants and it was the first of all in the art history on espas commentary.
Nowadays he is lecturing in Yeditepe University.
