Recha Charlotte Cohn was born on August 20, 1893, in
Charlottenburg, Berlin to Bernhard Cohn, a Jewish medical doctor, and Cäcilie Cohn. She was the youngest of seven children. Her brother, Emil Cohn, was a well-known writer and playwright, who published under the pseudonym, Emil Bernhard. Her eldest sister, Helene Cohn, founded the League of Jewish Women for Gymnastics and Sport in 1910, and performed gymnastics at the Eleventh Zionist Congress in Vienna, Austria, in 1913. In 1912 Cohn matriculated at the
Technische Hochschule in Berlin (today
Technische Universität Berlin); she graduated from the university's faculty of architecture in 1916, as one of the first women to do so. Between March 1917 and April 1919, Lotte worked in the reconstruction offices of Pillkallen, Tilsit and Gumbinnen in East Prussia. After returning to Berlin, she was employed as an assistant in the office of Zionist architect, Richard Michel. After accepting the job of first assistant to the architect and city planner, Richard Kauffmann in 1921, Cohn moved to
Jerusalem,
Mandatory Palestine, with her sisters, Helene and Rosa. Her brother, Max, followed two years later with his family, and her mother emigrated to Mandatory Palestine in 1932. Lotte Cohn died in
