Ernst Warschauer was born on May 26, 1889 in Breslau (now Wrocław, Poland). He was the oldest son of Sigismund Warschauer and Emma Warschauer, née Bernstein. In 1912 he received his doctorate in law from the University of Breslau. He married Agathe Karoline Rummler in 1919, whom he later divorced in 1935. Warschauer practiced law in Oels, Silesia until 1933 when laws enacted by the Nazi government prevented him from doing so. He moved to Berlin and married Claire (also known as Klara) Kantorowicz née Casper in 1938. In 1940 the family immigrated to New York, where Warschauer wrote and worked on restitution cases. Warschauer became friends with Julius Bab and kept correspondence with many other writers, including Alfred Polgar and Erich Kästner. Warschauer died on May 8, 1972.
