Heddy Kun graduated from the Budapest Academy of Fine Arts in 1956 and left for Israel, settling in Tel-Aviv, where she married Zeev Kun. For the past 60 years, Heddy has been painting with strong, bright colors. Her paintings bridge naturalistic and impressionistic styles, focusing on the changing light and the way the sun affects the painted object. Be it mountainscape, stormy sea, or a door – her effects are achieved by short and strong brush strokes. She has an extraordinary sense of color, discernible in her still life work with flowers, as well as her landscapes. She has had one-man shows in galleries all over Israel — the Rosenfeld Gallery, Tel Aviv, the Feferberg Gallery, Jerusalem, and the Weizman Gallery, Beer-Sheva— as well as in Europe, America, and Australia.

In March 2010, Heddy was granted a Lifetime Achievement Award by the International Association for Civil Rights.
