Hans Hermann Julius Hager 1816 – 1897 was a German Surgeon and Pharmacist, an advocate of homeopathy, and an honorary member of the American Pharmaceutical Association, Hager gave out the recipes of a number of secret remedies used by apothacaries, and analysed some of the common cosmetics of the day, which together with his interest in homeopathy was enough to earn him a terrible retribution from his orthodox colleagues.
Hans Hermann Julius Hager was born in Berlin on January 3, 1816, where his father was an army surgeon. He attended school in Torgan, he became a Surgeon to the staff of the Army and a Clinical Professor. Hager was an early proponent of the microscope.
The changeable life of his author, Hans Hermann Julius Hager, who was born in Berlin, is reflected in a contradictory way in pharmaceutical history. Although he never completed a study he reached the highest degree of pharmaceutical science as a genuine autodidact but was neglected and insulted during life time.
He died in very poor circumstances at Neuruppin, where he had come to live at his son’s place one year before his death.
Hans Herman Julius Hager’s Obituary is in the Proceedings of the American Pharmaceutical Association in 1897.
