[1][2] Endre's father, Béla Szász, was a doctor, and he seems to have inherited his artistic ability from his mother's (Erzsébet Susenka) family.

He used oil, acrylic, tempera, pencil, ink, charcoal, monotype, drypoint, lithography, etching and aquatint, and painted on several materials, like posters and porcelain.

He had several exhibitions all over the world, including the Museum of Modern Art (Mexico City), Auschwitz Museum (Poland), the Hungarian National Gallery (Budapest), and also exhibited in Madrid, Copenhagen, Brussels, Berlin, Rome, Oslo, Johannesburg, New Orleans, Los Angeles, San Francisco, Budapest, Amman (Jordan) and Tokyo.

[2] A Szász original also hangs in La Sebastiana, one of the homes of the famous Chilean poet and diplomat Pablo Neruda.

[5] Szász lived in Toronto, Canada 1970–1974, then in Los Angeles, California until 1982, when he went back to Hungary.
