Nathan Diamant

I have spent the past decade researching the art work of J.D. Kirszenbaum as well as its whereabouts.


This effort has resulted in the discovery of many works hidden from the public eye for decades. Many were found in the cellars of leading Museums in both national and private collections throughout France, Israel, Holland, Poland and Switzerland. Several were recently featured in two retrospectives exhibitions that took place this past year in major Israeli museums.

Dr. Igra joined Nathan Diament's endeavor to revive the lost legacy of his great uncle, Polish artist Jechezkiel David Kirszenbaum, in 2008. Toward this effort she has published a monograph on the artist (Somogy éditions d'art, Paris), an article on his exploration of "loss" for Ars Judaica and curated groundbreaking exhibitions on the artist—the first at the Museum of Art, Ein Harod, and the second at Beit Hatfutsot, Tel Aviv.
