A survivor of the Łódź Ghetto and Nazi concentration camps including Auschwitz, Dobroszycki lived in Poland after World War II where he obtained his education and worked as a historian.
According to Zachary Baker from Stanford, Dobroszycki became YIVO's "'research consultant to the stars'; he compiled a history of former New York mayor Ed Koch's ancestors and was a consultant to Barbra Streisand's film production of "Yentl" (an indirect Yiddish connection).
"Within the barbed-wire boundaries a microcosm arose... Children were born, stores were opened, a road constructed, hospitals set up, administrators employed, records kept.
It is these records, miraculously preserved in private libraries and underground caches, that provide the first detailed portrait of a Holocaust society.
In The Chronicle of the Lodz Ghetto, Editor Lucjan Dobroszycki, a survivor, presents an eerie and horrific scene told in terse entries, like a nightmare dreamed in pieces.
