In 1938, cooking teacher, restaurant proprietress, and vegetarian Fania Lewando published a Yiddish-language vegetarian cookbook. Vegetarish-Dietisher Kokhbokh: 400 Shpeizn Gemakht Oysshlislekh Fun Grinsn or, the Vegetarian-Dietetic Cookbook: 400 Recipes Made Exclusively From Vegetables, was the first Yiddish-language vegetarian cooking manual published Europe.
Shortly after Germany invaded Poland in 1939, Vilna fell under Soviet Union rule. The Nazis invaded soon afterward. We know Lewando and her husband Lazar tried to escape and were caught by Soviet soldiers. They were never heard from again.
