András Halász was born in Budapest, Hungary, 1946. He graduated from the Hungarian University of Fine Arts from the department of art and graphics, in 1976. As an art-student he organized avant-garde artists into a forum called the Rózsa Group which met in the Rózsa Espresso. It was here they performed fluxus events. After completing his studies Halász experimented with a number of different art forms like photograms, conceptual works, and performances. He frequently showed his works and participated at art events in alternative clubs, private homes, and community centres. His first one-man show of photos and photograms entitled Interest was in the Székesfehérvár House of Youth and Pioneers (Hungary) in 1978.

Halász left Hungary that same year because he felt his intellectual and artistic activity was stifled and could not have progressed further in the political-cultural environment of that time. He left for Paris, then for New York.

In New York he became deeply involved in painting. There, in 1982, he was awarded with a fellowship and studio space in P.S. 1 (Project Studios 1) by the NYC Art Council. It also provided frequent opportunities to show his paintings. His works were on show in numerous New York galleries, amongst them in the famous East Village galleries that introduced the most progressive movements in the 1980s.

Since 1990, he could visit legally his native country, Hungary, and regularly held exhibits in Budapest: From the late 1990s, he had fewer-and-fewer conceptual elements and focused on pictorial vision.

Around the year 2000, he started to paint still lifes and interiors with objects of his daily life that were not particularly interesting or beautiful: table, chair, ladder, wardrobe, washing machine, bubble wrap. Halász eliminates the artistic look yet his method of painting is strictly conventional. His palette is reduced to white, grey, and brown, which colours underline a sort of austere, puritanical mindset and rather evoke a metaphysical atmosphere.

In 2005, he moved back to his native country and was given a position as a Professor of Art at the Hungarian University of Fine Arts, Budapest, the same university in which he studied.
