author
1770–1849
An early-19th-century German medical writer, he is remembered today for a concise but unusual health treatise that reflects the period’s blend of anatomy, social ideas, and practical advice.

by Johann Georg Klees
Little biographical information about Johann Georg Klees appears to be widely available online, but standard library and catalog records identify him as a German author who lived from 1770 to 1849. He is chiefly associated today with Über die weiblichen Brüste, a medical work that has been preserved in major public-domain and library collections.
That book focuses on the anatomy, function, and care of women's breasts, showing the concerns of medicine in the early 1800s as well as the era's attitudes toward beauty, health, pregnancy, and nursing. Modern readers are most likely to encounter Klees through digitized editions rather than through a large surviving body of biographical writing.
Because confirmed details about his life are limited in the sources found here, the safest picture is of a physician-author whose reputation now rests on a specialized medical text from the German-speaking world of the early nineteenth century.
