Bergner designed scenery and costumes for the Yiddish and Hebrew theatres, particularly for the plays of Nisim Aloni, and has illustrated many books. The acme of Bergner's paintings is his allegorical works; he uses kitchen tools such as squashed pots, oil lamps, wrecks and cracked jugs and he anthropomorphizes them. These old instruments symbolize distorted and poor world of wars, secrets and darkness. one of his student was Nurit Shany, a painter and a multidisciplinary Israeli artist.
