About the author
Trained as an apothecary, Hermann Hager was born in Berlin in 1816 and passed the state examination in 1841. After running a pharmacy in Fraustadt for years, he later devoted himself mainly to writing and editorial work, building a reputation as one of the most useful pharmaceutical authors of his time.
He is especially associated with Hager's Handbuch der pharmaceutischen Praxis, a large, practical encyclopedia that became a standard reference in German pharmacies. He also edited the Pharmazeutische Centralhalle in Berlin and wrote on pharmaceutical, chemical, and botanical subjects, with particular value placed on his analyses of so-called secret remedies.
Rather than writing only for specialists in theory, Hager focused on the everyday needs of pharmacists: testing substances, judging quality, and working carefully with medicines and materials. That practical spirit is a big reason his name remained familiar long after his death in 1897.
