Born in Tel-Aviv, Israel, in 1939, he is a sculptor and art professor, internationally recognized for his subterranean sculptures that were publicly exhibited for the first time at the 1980 Venice Biennale.
Ullman’s sculptures, some of which barely protrude from the ground, deal with universal themes such as the meaning of place and home, absence and emptiness. They are derived from both the political and existential local reality in Israel, and the post-minimalist worldview of sculpture; being simultaneously celestial and earthbound, metaphysical but sensual and tactile.
His sculptures convey sensations of fortification, self-defense, death, despair and decadence, yet at times hope and aspiration for religious elevation. In that sense, Ullmann's sculptures represent an essential aspect of the modern Israeli existence.
One of Ullman’s most famous works is the “Bibliotek” memorial on Bebelplatz square in Berlin, where the Nazi book burnings began in 1933.
