Limann worked at the Institute as second secretary of the "Scientific-humanitarian Committee" (Wissenschaftlich-humanitäres Komitee) from 1923 to 1929. He systematized the Committee-archives and organized the press and public relations service. In 1928, he lectured students taking part in the Institute's training programme.
From 1928 to 1929, he lived with his friend, Richard Linsert, on the Institute's ground-floor.
After they moved out and took lodgings elsewhere, Limann set up an arts and crafts shop in their new flat.
