(AP) — A two-year project to document the records from the Menninger Foundation archives has been completed by the Kansas Historical Society.

The records date from 1644 to 2002 and include the papers of famed Topeka psychiatrists C.F., Roy, Walter, Karl and William Menninger. They also include manuscripts from Sigmund Freud and Florence Nightingale.

Selected documents from the 2,500-cubic-feet of records are available for viewing on the historical society’s Kansas Memory digital archives.

The Menningers founded their Topeka mental health clinic in 1925, growing to international fame for its hospital and training programs.

The Menninger Clinic campus closed and relocated in 2003 to Houston to become part of the Baylor College of Medicine.
