Berl Kagan (Kahn) was a Jew­ish writer, lex­i­cog­ra­ph­er, bib­li­og­ra­ph­er, edi­tor, and Holo­caust sur­vivor whose post­war schol­ar­ship con­tributed sig­nif­i­cant­ly to the preser­va­tion and recon­struc­tion of East­ern Euro­pean Jew­ish his­to­ry and Yid­dish lit­er­a­ture. Kagan’s schol­ar­ly con­tri­bu­tions are of con­sid­er­able sig­nif­i­cance to the study of Jew­ish his­to­ry and Yid­dish lit­er­a­ture. His Lex­i­con of Yid­dish Writ­ers (1986), received the Nation­al Jew­ish Book Award, and remains one of the most com­pre­hen­sive ref­er­ence works on Yid­dish lit­er­ary figures.
