Career
Born 16 January 1871, Mainzer wrote his doctoral disseration on wandering spleen. In the 1890s he worked at the Berlin clinic of the gynecologist Leopold Landau. Mainzer had artistic connections and historical interests.
After a hand injury meant that he could no longer perform surgery, he turned to writing about antiquity.
His biography of Julius Caesar was translated into French and English, and widely reviewed. The book inspired Thornton Wilder to write his own novel about Caesar, The Ides of March.
Mainzer and his family were helped to escape to England by the daughter of Wilhelm and Hanna Solf, the Countess So"oa"emalelagi "Lagi" von Ballestrem-Solf, who escorted them with their jewellery hidden in the lining of her clothes. Mainzer died 3 January 1943.
