Lou Eisler recorded the stations of her husband’s emigration in her own handwriting. Composer Hanns Eisler met Lou in 1933 when he was staying in Czechoslovakia. At the end of 1933 she visited him in Paris and was his constant companion from 1934 on. Therefore, she knew nearly all the stations of Eisler’s emigration from personal experience. In January 1937, Eisler went to Spain to support the International Brigade in the civil war by composing for them. This is also referenced in the little poem by Ludwig Renn, a commander. 

In the autumn of the same year, Eisler went on a concert tour of Czechoslovakia. He married Lou on 7 December 1937 in Prague. In her incorrect English, she makes a list of their ever-changing locations; her writing varies, with German words sometimes making an appearance. She even mentions the date of her own wedding in the style of a chronicler, not without mentioning the date of Eisler’s divorce from his first wife: “Divorced first wife May 14, 1935.” Denmark is mentioned often; during these stays Eisler met the writer Bertolt Brecht, whom he had known since 1927. There they continued their collaboration with works such as the requiem Lenin, the German Symphony and various songs.
