His artistic work is characterized by a contemplative approach that the famous Israeli writer describes as "calm, whispered, but overwhelmed with nostalgia, compassion, and warmth." His exhibitions, based on emotion, disappearance, and absence, question what remains of the passing of a human being and are regularly enriched with beautiful books nourished by philosophical reflections.
Alongside his artistic practice, Kleinmann conducts a theoretical reflection on contemporary art, materialized by the publication of the essay "Interrogations sur l'art contemporain" by Éditions de Paris Max Chaleil in 2018. This intellectual approach fuels his creation and testifies to his commitment to contemporary aesthetic debates.
His pictorial and sculptural works have an international reputation, exhibited in prestigious galleries and institutions across all continents: Paris, Milan, Berlin, London, Barcelona, Lausanne, Stockholm, Brussels, Havana, Berkeley, Seoul, Tokyo, Moscow, and Beijing. This global recognition is accompanied by a considerable editorial output documenting his career.
With Hastaire, he co-founded the international group of painters "Mémoires," a collective initiative that extends his reflection on the transmission of memory in contemporary art. Based in Paris, where he continues to live and work, Kleinmann perpetuates an art of remembrance rooted in the universality of human experience.
