Dr. Doron Keren, a retired den­tist, dis­cov­ered his pas­sion project after hav­ing his grandfather’s, Igna­cy Chiger, mem­oir trans­lat­ed from Pol­ish to Eng­lish. He is ded­i­cat­ed to pre­serv­ing and shar­ing a vital con­tri­bu­tion to Holo­caust lit­er­a­ture, ensur­ing that the hor­rors and hero­ism of the era are nev­er for­got­ten. Beneath the Light­less Sky now stands as a pow­er­ful tes­ta­ment to resilience and survival.
