1770–1849
A German physician and medical writer from Frankfurt am Main, he is best remembered today for an early 19th-century book on women’s breast health that blends anatomy, practical advice, and the medical thinking of its time.

by Johann Georg Klees
Born in 1770 and deceased in 1849, Johann Georg Klees was a German doctor and author associated with Frankfurt am Main. Catalog records and library sources identify him as the writer of several medical works, including publications on obstetrical instruments and childbirth.
His best-known surviving work is Über die weiblichen Brüste ("On Women’s Breasts"), published in the early 1800s and preserved by major digital libraries. The book discusses the structure, function, care, and illnesses of the breast, giving modern readers a window into how physicians of his era approached women’s health.
Although little widely available biographical detail appears to survive online, Klees stands out as one of those lesser-known medical authors whose books still offer valuable insight into everyday medicine, gender, and health concerns in German-speaking Europe around 1800.
