Sonja Gerlach was born in Hannover in 1936. She did a secondary school teaching degree (Staatsexamen) in music and mathematics in Berlin. From 1965 to 1999 she was a research associate and editor at the Joseph Haydn-Institut in Cologne. In addition to her work as an editor and researcher she addressed questions concerning the chronology of Haydn’s symphonies. She is also very interested in problems of ascertaining authenticity of works in Haydn’s different genres.
In 2000 she retired and moved to Munich where she now lives.
