Lev Nussimbaum

Historians and literary critics who knew these subjects well discredited Essad Bey as a reliable source. Today, historians disregard books published under this name and rarely quote him, though the topics Essad Bey chose to write about are still critically relevant. The fact that Essad Bey was so prolific calls into question the authorship of these books and whether Essad Bey was primarily operating as a broker and doctoring manuscripts and marketing them under his pseudonym, which had become famous. In 1934, his agent warned him to slow down and take a year off between books so that he would not appear to be so prolific. That year no books were published in German – only two novellas in Polish.
